Before any embankment is placed all clearing, tree removal, sod and topsoil over the entire area shall be performed as directed by the Engineer. Clearing shall consist of the removal and disposal of all obstruc- tions such as foundations, walls, fences, buildings, rubbish, etc., to a depth of at least twelve inches below subgrade elevation. Sod within the area shall be removed to a depth of six inches. Trees except those designated to be saved and all stumps shall be removed to a depth of at least eighteen inches below the subgrade elevation. All trees designated to be saved shall be protected care- fully during clearing and subsequent construction operations. Topsoil shall be excavated and stockpiled as directed by the Engineer. Each layer of the embankment material not to exceed eight inches in loose depth shall be disked sufficiently to break down oversized clods, thoroughly mix the different materials, secure a uniform moisture content and insure uniform density and proper compaction. Each layer shall be thoroughly compacted by roller or vibratory equipment suitable for the type of embankment material. 4. Borrow or Excess Excavation. In the event sufficient suitable filling material is not obtained within the limits of this contract to provide all the embankment required, the contractor shall furnish such additional filling material borrow to complete the designated embankment. All borrow shall be of the same type of soil as the embankment material and shall be approved by the Engineer before being placed. 5. Subgrade. The bottom of the excavation for the pavement or top of the fill shall be known as the pavement subgrade and shall conform to the lines, grade and cross - sections shown on the plans. All soft and yielding material and other portions of the subgrade which will not compact readily when rolled or tamped shall be removed as directed and replaced with suitable material placed and compacted as specified herein. The subgrade shall have uniform density and be compacted at or slightly above the optimum moisture content. In the absence of Subdivision Specifications Page 6. standard testing, a reasonable evaluation of moisture content may be made by squeezing a ball of damp soil in the hand. If the ball is so dry that it crumbles easily, additional water should be mixed into the soil. If it is so wet that free water comes to the surface when kneaded, the subgrade should be permitted to air out before final rolling. The subgrade shall be thoroughly compacted with suitable equipment. All sewer trenches and structure excavations shall be backfilled to natural or finished grade as soon as conditions permit. All backfill shall be compacted with mechanical tampers in layers of not over six inches loose material. Vibratory compactors that are small enough to operate within the limited area are very satisfactory. The subgrade shall be finished in least one day's progress in advance all times. Concrete shall not be placed upon or other subgrade, the stability of Engineer, unsuitable for the placemi an acceptable condition for at of the pavement construction at a soft, spongy or frozen subgrade which is, in the opinion of the Dnt of concrete. The subgrade shall be in a moist condition at the time the concrete is :placed. It shall be thoroughly wetted a sufficient time in advance of the placing of the concrete to insure that there will be no puddles or pockets of mud when the concrete is placed but shall not be allowed to dry out before the concrete is placed. Immediately prior to placing the concrete, the subgrade shall be tested for conformity with the cross - section shown on the plans by means of an approved template riding on the side forms. If necessary, material shall be removed or added, as required, to bring all portions of the subgrade to the correct elevation. It shall then be thoroughly compacted and again tested with the template. Concrete shall not be placed on any portion of the subgrade which has not been tested for correct - elevation. The subgrade should also be cleared of any loose material which may have fallen upon it. 6. Protection of Subgrade. The finished subgrade shall be main- tained in a smooth and compacted condition until the concrete has been placed. The mixer, ready -mix trucks, or other equipment shall not operate between the forms in the paving lane unless conditions of the job will not permit operation from the shoulder or outside the lane. Mixer or ready -mix trucks shall not be permitted to operate from previously paved lanes until the pavement is at least seven days old or a flex- ural strength of 550 psi is attained with AASHO Standard Method T 23 and T 97. If it is necessary to operate trucks between the forms and they cause rutting or displacement of the subgrade material, either lighter trucks shall be used or suitable runways shall be provided. The contractor shall re -roll or hand -tamp the subgrade to correct any ruts or other objectionable irregularities which may have been caused by the trucking of materials. Subdivision Specifications Page 7. A berm shall be graded between the curb and sidewalk, or property line.where there are no existing sidewalks, in a neat, workmanlike manner. All excess concrete and debris shall be removed from the excavation behind the curb line before backfilling. C. Concrete Pavement with Integral Curb 1. Scope.

The entire contents of the drum shall be discharged before recharging. The volume of the mixed materials per batch shall not exceed the man- ufacturer's guaranteed capacity (110 per cent of rated capacity) of the mixer. 6. Time of Mixing. The mixing of each batch shall continue for not less than one minute after all materials, excepting water, are in the mixer. All mixing water shall be introduced in the drum before one - fourth of the mixing time has elapsed. The mixer shall rotate at the rate recommended by its manufacturer. The mixer shall be provided with a batch timing device which shall be subject to inspection and adjustment by the Engineer at any time. 7. Ready -Mixed Concrete. Ready -mixed concrete shall be mixed and transported in accordance with the current ASTM Specifications for Ready -Mixed Concrete (Designation C -94). Any concrete which is not plastic and workable when it reaches the subgrade shall be rejected. When construction conditions are such that it is absolutely necessary for trucks hauling concrete to operate on the grade between forms they shall not back over previously deposited concrete. 8. Remixing. Concrete or mortar that has stiffened but not set may be used after remixing if it is plastic enough to be compacted in the forms. Water must not be added at time of remixing. 9. Measuring Air Content. The air content of freshly mixed air - entrained concrete shall be checked at least twice daily. Concrete with air contents above or below the amount specified in Paragraph E2 shall be corrected by adjustments in the mix design or quantities of air - entraining admisture being used.

F. Forms. Forms shall be made of metal and shall have a depth equal to or greater than the prescribed edge thickness of the pave- ment slab, except when curb form is added after machine finishing. They shall have a base width of not less than eight inches for all Subdivision Specifications forms eight inches or more inches in height shall have The minimum length of each Each section of form shall Page 11. in height. All side forms less than eight a base width of not less than six inches. section of form used shall be ten feet. be straight, free from bends or warps. The maximum deviation of the top surface of any section shall not exceed one - eighth inch, or the inside face not more than one - fourth inch from a straight line. The method of connection between sections shall be such that the joint thus formed shall be free from movement in any direction. Forms shall be of such cross - section and strength and so secured as to resist the pressure of the concrete when placed, and the impact and vibration of any equipment which they support, without springing or settlement. Each ten foot length of form shall have at least three form braces and pin sockets which shall be spaced at intervals of not more than five feet, having the end brace and socket not more than six inches from the end of the form. Approved flexible forms shall be used for construction where the radius is 150 feet or less. 1. Setting Forms. The subgrade under the forms and cut to grade so that the form when set will be for its entire length at the specified elevation. joined neatly and in such a manner that the joints or movement in any direction. Forms shall be set, for at least one day's construction ahead of the a concrete. The supply of forms shall be sufficient remaining in place for at least twelve hours after been placed. All forms shall be cleaned and oiled used. shall be compacted uniformly supported Forms shall be are free from play as herein specified, -Itual placing of the to permit their the concrete has each time they are 2. Grade and Alignment. The alignment and grade elevations of the forms shall be checked by the contractor's engineer and the necessary corrections made by the contractor immediately before placing the concrete. When any form has been disturbed or any subgrade thereunder has become unstable, the form shall be reset and rechecked. 3. Placing Concrete. The concrete shall be mixed in quantities required for immediate use and shall be deposited on the subgrade to the required depth and width of the construction lane in successive batches and in a continuous operation without the use of intermediate forms or bulkheads. The concrete shall be placed as uniformly as possible in order to minimize the amount of additional spreading necessary. While being placed, the concrete shall be spaded or vibrated and compacted with suitable tools so that'the formation of voids or honeycomb pockets is prevented. The concrete shall be especially well spaded or vibrated and temped against the forms and along all joints. Care shall be taken in the distribution of the concrete to deposit a sufficient volume along the outside form lines so that the curb section can be consolidated and finished simultan- eously with the slab. No concrete shall be placed around manholes or other structures until they have been brought to the required grade and alignment. - Subdivision Specifications Page 12. 4. Cold Weather Concreting. Except by specific written authoriza- tion concreting shall cease when the descending air temperature in the shade and away from artificial heat falls below 400 F. It shall not be resumed until the ascending air temperature in the shade and away from artificial heat rises to 350 F. H. Consolidating and Finishing. 1. General. The pavement shall be struck off and consolidated with a mechanical finishing machine or by hand - finishing methods. When a mechanical finishing machine is used, the concrete shall be struck off at such a height that after consolidation and final finish- ing it shall be at the exact elevation as shown on the plans. A depth of at least two inches of concrete shall be carried in front of the strike -off screed for the full width of the slab, whenever the screed is being used to strike off the pavement. The finishing machine shall be provided with a screed which will consolidate the concrete by pressure. The concrete shall, through the use of this machine, be brought to a true and even surface, free from rock pockets, with the fewest possible number of sages of the machine. The edge of the screeds along the curb line may be notched out to allow for sufficient concrete to form the integral curb. Hand - finishing tools shall be kept available for use in case the finishing machine breaks down. When hand - finishing is used, the pavement shall be struck off and consolidated by a vibrating screed to the exact elevation as shown on the plans. When the forward motion of the vibrating screed is stopped the vibrator shall be shut off, it shall not be allowed to idle on the concrete. 2. Longitudinal Floating. After the concrete has been struck off and consolidated it shall be further smoothed by means of a longitudi- nal float. If a mechanical longitudinal float is not used a longitud- inal hand float shall be operated from foot bridges spanning the pave- ment and shall be worked with a wiping motion, parallel to the pave- ment centerline, and passing from one side of the pavement to the other. Movement ahead along the centerline of the pavement shall be in successive advances of not more than one half of the length of the float. The float shall be not less than twelve feet in length and six inches in width and shall be properly stiffened and provided with handles at each end. 3. Scraping. After the passage of the longitudinal float, the pavement shall be scraped with a straightedge 10 feet long, equipped with a handle to permit it to be operated from the edge of the pave- ment. The straightedge shall be operated so that any excess water and laitance are removed from the surface of the pavement. 4. Straightedging. After the longitudinal floating and scraping have been completed and any excess water removed, but while the con- crete is still plastic, the slab surface shall be tested for smooth- ness with a ten foot straightedge swumg from handles three feet longer than one -half the width of the slab. The straightedge shall be placed on the surface parallel to the centerline of the pavement ..Subdivision Specifications ' Page 13. and at not more than five -foot intervals transversely. After each test the straightedge shall be moved forward one -half its length and the operation repeated. When irregularities are discovered they shall be corrected by adding or removing concrete. All disturbed places shall be floated with a wooden float not less than three feet long and not less than six inches wide, and again straightedged. The pavement surface shall have no depression in which water will stand. The use of the long- handled wood floats shall be confined to a minimum. They may be used behind the longitudinal float to correct surface unevenness not taken care of by the longitudinal float, but shall not be used to float the entire surface of the pavement in lieu of or supplementing the use of the longitudinal float. 5. Edging. Before the final finishing is completed and before the concrete has taken its initial set, the edges of the slab and curb shall be carefully finished with an edger of the radius shown on the plans. 6. Final Surface Finish. A burlap drag shall be used as the final finishing method. The drag shall be at least three feet in width and long enough to cover the entire pavement width. It shall be kept clean and saturated while in use. It shall be laid on the surface of the pavement and dragged forward in the direction in which the pavement is being laid. The curb shall have the same final finish as the pavement. The final surface of the concrete pavement and curb shall have a uniform gritty texture free from excessive harshness and true to the grades in the final finishing procedure as required to produce the desired final surface texture. 2. Integral Curb. Integral curbs shall be required along the edges of all street pave- ment as indicated on the plans, except at such locations as the engineer may direct. Depressed curbs shall be provided at all drive- way entrances and at such other locations as designated by the engineer. The integral curb shall be constructed immediately following the finishing operation. Special care shall be taken so that the curb construction does not lag the pavement construction and form a "cold joint ". Steel curb forms shall be required to form the backs of all curbs except where street returns of small radius or other special sections make the use of steel forms impractical. In placing concrete curb, sufficient spading shall be done to secure adequate bond with the paving slab and eliminate all voids in the curb. Curbs shall be formed to the cross - section as shown on the drawings with a mule or templates supported on the side forms and a wood float not less than four feet in length. ..Subdivision Specifications Page 14. The finished surface of the curb and gutter shall be checked with the use of the ten feet straightedge and corrected if necessary. While the concrete is still plastic the drainage at the gutter should be- checked by pouring water at the gutter summit and observing its flow to the inlet. In order to prevent damage to the concrete surface water should be poured onto a piece of burlap or curing paper. J. Curing. Concrete shall be cured by protecting it against loss of moisture, rapid temperature change, and from rain, flowing water, and mechanical injury for a period of not less than five days from the beginning of the curing operation. Moist curing, waterproof paper, white polyethy- lene sheeting, liquid membrane compound or a combination thereof may be used for curing. Immediately after finishing operations have been completed, the entire surface of the newly laid concrete shall be covered by the curing medium which is applicable to local conditions and approved by the engineer. The edge of concrete slabs exposed by the removal of forms shall be protected immediately to provide these surfaces with continuous curing treatment equal to the method selected for curing the slab surface and to prevent injury to pavement edges. The use of a covering material which contains or becomes contaminat- ed with sugar in any form, tannic acid, or any other substance con- sidered detrimental to Portland cement will not be permitted. The initial curing medium shall be effective and shall be applied so as to prevent checking, cracking, and the appearance of dry spots in the surface of the concrete. The contractor shall have the equipment needed for adequate curing at hand and ready to install before actual concrete placement begins. In all cases in which the curing medium requires the use of water, the curing shall have prior right to all water supply. Failure to provide sufficient cover material of the type selected, failure to maintain saturation for the entire curing period in the moist - curing methods, lack of water to adequately care for both curing and other requirements, or other failures to comply with curing requirements shall be cause for immediate suspension of concreting operations. 1. Moist Curing. Moist curing shall be accomplished by covering of burlap, cotton mats or other approved fabric mat, used singly or in combination. Curing mats shall be thoroughly wet when applied and kept continu- ously wet and in intimate contact with the pavement surface for the duration of the moist curing period. Other fabric mats shall conform in design and shall provide a curing medium at least equal to cotton mats. Cotton mats, other fabric mats, and burlap strips shall be furnished in the widths or lengths, after shrinkage, required to cover the entire width and edges of the pavement lane, mats or burlap shall be lapped at joints between adjacent sheets to prevent drying of this location. Moist curing when used as initial curing shall be continued for not less than twenty -four hours. 2. Waterproof Paper Curing. The surface of the concrete shall be wetted with a fine spray of water and then covered with the waterproof Subdivision Specifications ' Page 15. paper. The paper shall be in pieces large enough to cover the entire width and edges of the slab and shall be lapped not less than twelve inches. Paper shall be adequately weighted to prevent displacement or billowing due to wind. Paper folded down over the side of the pave- ment edges shall be secured by a continuous bank of earth. Tears or holes appearing in the paper during the curing period shall be immediately repaired. 3. White Polyethylene Sheeting. White polyethylene sheeting shall meet the specifications under Paragraph D13 and the following provisions of this paragraph. 4. Liquid Membrane Curing Compound. Pigmented liquid membrane curing compound shall meet the specifications under Paragraph D13. The curing compound must be applied to cover the surface completely and uniformly at a rate which will achieve the performance requirement specified in AASHO Specifications M -148. This method of curing shall be applied immediately behind the final finishing operation or after the initial curing when a combination of methods are used. Failure to provide complete and uniform coverage at the required rate will be cause for discontinuance of this method of- curing and the substitution of one of the other approved methods. The compound shall be kept agitated to prevent the pigment from settling. Special care shall be taken to apply the curing compound to the pavement edges immediately after the forms have been removed. K. Joints. Longitudinal and transverse joints shall be constructed as shown on the plans. Longitudinal joints are those points parallel to the lane of con- struction. They may be either intermediate center joints or the construction joints between construction lanes. Transverse joints shall be contraction joints or construction joints. Construction joints are put in transversely wherever con- struction operations require them. Expansion joints may be either longitudinal or transverse. They are used only where specifically shown on the plans. The edges of the pavement and those joints where such edging is shown on the plans shall be founded with an edger having a radius of not larger than 1/8 inch. Traverse joints except keyed and tied con- struction joints shall be continuous across the entire paved area including the curb. 1. Transverse Joints. Transverse joints shall be contraction, expansion or construction joints. Contraction and expansion joints shall be placed as indicated on the plans and construction joints wherever construction may require them. They shall make a right angle with the centerline of the pavement and surface of the subgrade. 2. Transverse Expansion Joints. Expansion joints, where shown on the plans shall conform to the specification in Paragraph D8. They shall extend the entire width of the pavement and from the subgrade Subdivision Specifications I Page 16. to one inch below the surface of the pavement. They shall be of the dimensions and spacing as shown on the plans. The filler shall be held accurately in place during the placing and finishing of the con - crete by a bulkhead, a metal channel cap or other approved method. Under no circumstances shall any concrete be left above the expan- sion material or across the joint at any point. Any concrete spanning the ends of the joint next to the forms shall be carefully cut away after the forms are removed. Before the pavement is opened to traffic the groove above the filler shall be cleaned and sealed with specified joint sealing material covered under Paragraph D9. 3. Transverse Contraction Joints. Transverse contraction joints shall be of the sawed, formed dummy groove or premolded strip type. 4. Transverse Sawed Contraction Joints. When transverse contrac- tion joints are to be formed by sawing, care must be taken to saw the grooves soon after placing to prevent the formation of cracks due to contraction of the slab. All transverse joints shall be sawed at least 1/4 of the slab depth. Any procedure for sawing joints that results in premature and uncontrolled cracking shall be revised immediately by adjusting the time interval between the placing of the concrete and the cutting of the joints. 5. Transverse Formed Dummy Groove Joints. Transverse dummy groove joints shall be formed by a groove or cleft in the top of the slab of the dimensions shown on the plans. The groove made in the plastic concrete by a suitable tooling device, shall extend vertically downward 1/4 of the slab depth from the surface and shall be true to line. 6. Transverse Premolded Strip Joints. Transverse premolded strip shall be of the proper dimensions as shown on the plans. The premold- ed filler is placed in a vertical groove formed to receive it. The top of the filler should be flush with the pavement surface. 7. Transverse Construction Joints. Transverse construction joints of the type shown on the plans shall be placed wherever the placing of concrete is suspended for more than thirty minutes. A butt type joint with dowels shall be used if the joint occurs at the location of a contraction joint. Keyed joints with tiebars are used if the joint occurs at any other location. 8. Dowels. If joints are to be equipped with dowels they shall be of the dimension and at the spacing and location indicated on the plans. They shall be firmly supported in place, accurately aligned parallel to the pavement grade and the centerline of the pavement by means of a dowel support which will remain in the pavement and will insure that the dowels are not displaced during construction. One - half of each dowel shall be painted and greased and in expansion joints one end shall be equipped with a tight fitting sleeve of the dimensions shown on the plans conforming to Paragraph D12. Subdivision Specifications Page 17. 9. Longitudinal Joints. Longitudinal joints shall be placed as shown on the plans. They shall be of the sawed, dummy groove pre - molded strip, or the keyed construction type. Joints between con- struction lanes shall be the keyed construction type. 10. Longitudinal Center Joint. Longitudinal center joints shall be of the sawed, formed dummy groove or premolded strip type. 11. Sawed Longitudinal Center Joints. Sawed longitudinal center joints shall be sawed grooves made with a concrete saw after the concrete has hardened. The saw cut shall be at least 1/4 of the slab depth. The joint may be sawed at any time prior to the time the pave- ment is open to traffic. These joints are otherwise formed in the same manner as the transverse sawed joints - Paragraph K4. 12. Longitudinal Formed Dummy Groove Joints. Longitudinal dummy groove joints are formed in the same manner described for Transverse Formed Dummy Groove Joints, Paragraph K5. 13. Longitudinal Premolded Strip Joint. Longitudinal premolded strip joints are formed in the same manner described for Transverse Premolded Strip Joints, Paragraph K6. 14. Longitudinal Construction Joints. Longitudinal construction joints (i.e., joints between construction lanes) shall be of the dimensions shown on the plans. The key shall be constructed by placing a deformed metal plate against the form when the first lane adjacent to the joint is placed. This metal plate shall be removed with the form. When placing the second slab, care must be taken that no concrete is left to overhang the lip formed in the first slab by the edging tool. 15. Tiebars. Tiebars or tiebolts when shown on the plans shall be of deformed steel and of the dimensions and at the spacing specified. Tiebars shall be firmly supported by subgrade chairs or so installed as not to be displaced during construction operations. 16. Joint Sealer. After the curing period all sawed and dummy groove joints in the pavement shall be cleaned and sealed with mater- ial meeting the requirements of Paragraph D9. All foreign material, joint sawing residue, dirt and curing membrane shall be removed. Joints shall be slightly under- filled (about 1/4 inch) to prevent extrusion of sealer. Any excess material should be removed from the pavement surface as soon after sealing as possible. 17. Integral Curb Joints. In the construction of transverse joints of concrete integral curb pavement, special care must be taken to see that all transverse points extend continuously through the pavement and curb. L. Structures. All manholes, catch basins, or structures of a permanent nature encountered in the areas to be paved shall be raised or lowered as the case may be, to the surface of the new pavement and the necessary expansion material as specified in Par. D8 placed around each structure for the full depth of the slab and of the thickness shown on the plans. Subdivision Specifications Page 18. M. Cold Weather Protection. When concrete is being placed in cold weather and temperature may be expected to drop below 35 °F. a supply of straw, hay, insulated curing blankets or other suitable material shall be provided along the line of the work. Membrane cured pave- ment shall be protected with waterproof paper if straw is to be placed soon after the pour to prevent straw from embedding in surface. At any time when the air temperature may be expected to reach the freez- ing point during the day or night, the material so provided shall be spread over the concrete to a sufficient depth to prevent freezing of the concrete. Concrete shall be protected from freezing temperatures until it is at least five days old. Concrete injured by frost action shall be removed and replaced at the contractor's expense. N. Protection and Opening to Traffic. The contractor shall pro- tect the pavement against all damage prior to final acceptance of the work by the owner. Traffic shall be excluded from the pavement by erecting and maintaining barricades and signs until the concrete is at least seven days old, or for a longer period if so directed by the engineer.- The pavement shall not be used at any time within this period for transporting of operating equipment. As a construction expedient, the subgrade planer, concrete finishing machine, and similar equipment may be permitted to ride upon the edges of pre- viously constructed slabs provided the concrete is more than seventy - two hours old, and the equipment has rubber -tired wheels to run on the finished slab. Further provided that two coats of boiled linseed oil mixture be applied to concrete pavement constructed after September 15th which would be opened to traffic prior to the following April 15th to minimize spalling from salt action. 0. Optional Construction Equipment. 1. Slip -form Paver. In lieu of the construction methods described in the preceding section of the specifications, the contractor may use a slip -form paver. When the slip -form paver is used, all reference in the preceding sections of this specification referring to forms shall be deleted. Slip -form pavers shall be equipped with vibratory and tamping bar assemblies which are effective over the full width of the pavement. The paver shall also have a metal float with a bullnozed front end for the full width of the pavement, excluding curbs, which will extrude the concrete under pressure.

The requirement for longitudinal floating (Par. H2) shall be deleted. 2. Subgrade. The subgrade shall be brought to the proper grade and cross - section by means of a properly designated and operated machine. The subgrade shall comply with applicable sections of this specification. If any traffic is allowed to use the prepared sub- grade, some device, satisfactory to the engineer, shall be provided Subdivision Speclications ' Page 19. for checking and correcting the subgrade immediately ahead of placing the concrete. The subgrade work, especially the path on which the tracks of the paver ride, must be done carefully and accurately as its degree of precision greatly affects the resulting smoothness of the pavement surface. 3. Placing. Concrete shall be uniform slump and adequately supp- lied in front of the paver. The rate of progress shall be controlled so that the forward movement of the paver will be as nearly continuous as practicable. If it is necessary to stop the forward movement of the paver the vibrator and tamping elements shall also be stopped immediately. Care must be taken to see that a sufficient supply of concrete passes around the float and the belt along the form line to form the integral curb where shown on the plans. 4. Final Finishing and Testing. Final finishing operations shall conform to the applicable sections of this specification. Strength and testing requirements to be in accordance with Section 408 of the Standard Specifications. 5. Driveway Approaches - Other than Residential or Dwelling.

The center line of all driveways must be approximately at right angles to the curb line of the pavement in the public street for a distance of at least ten feet from said curb line. Grade. All driveways shall be so graded between the gutter and the sidewalk that it will not be necessary to change the established grade of either and will not elevate or depress any portion of either. No part of said driveway shall extend beyond the curb line in such a manner as to change the grade of said gutter or obstruct the free flow of water in said gutter. Where elevations or depressions are necessary in the parkway strip between the curb and walk, said park- way shall be graded on both sides of the driveway to a distance sufficient to create a gradual ascent or descent. At no time shall the gradient exceed one foot vertical to ten feet horizontal. Curb and Gutter. Combined curb and gutter and separate curbing shall be entirely removed for the full width of the driveway opening at the curb line. If an existing joint in said curb is within five feet of the end of the driveway opening, the existing curbing, etc., shall be removed to said joint, otherwise said combined curb and gutter or separate curbing shall be cut, making a neat edge at right angles to the edge of the pavement and vertical. Integral curbing, which is that type placed with the "V" pavement and moulded as an integral part of it, must be removed for the full depth from the top of the curb to the bottom of the pavement. The edge shall be cut as above described. No combined curb and gutter, straight curb or integral curb shall be removed within five feet of a public cross walk. Ditches.

Method: The method of measuring the materials for the concrete or mortar, including water, shall be one which will insure separate and uniform proportions of each of the materials at all times. 2 Proportions: The concrete shall be mixed in the proportions which, when the proaer amount of water is added, will produce a mini- mum compressive strength of eighteen hundred pounds per square inch after seven days and a minimum compressive strength of three thousand pounds per square inch after twenty- -eight days when curOd under field conditions.. 3. Admixtures: Air Entraining Admixtures shall not be added to concrete mixtures in the field without the approval of the engineer., If such approval is granted, the admixture shall conform to Section 11 -- and shall be added in the amount and in the manner prescribed by the manufacturer so that the air content of the concrete shall not be less than three nor more than six percent, IV. MIXING: 1. Method: All concrete shall be mixed in a stationary batch mixer or truck mixer unless manual mixing is authorized by the en=; ine er. . (a) If a stationary batch mixer is used the mixer drum shall be of adequate size to accommodate the maximum batch and shall conform to the Concrete Mixer Standards adopted by the Mixer 14anufacturers Bureau of the Associated General Contractors of America. The mixer drum shall be rotated at the rate specified by its manufacturer. When a stationary batch mixer is used for complete mixing, the minimum mixing time for mixers of one cubic yard capacity or less shall be one minute; for larger capacities of mixtures the mixing time shall be increased at the rate of one - quarter minute for each additional cubic yard or fraction thereof. The mixing time shall begin when the correct proportions of cement and aggregates are placed in the mixer.. A portion of the water shall be placed in the mixer in advance of the cement and aggregates. The full amount of water required to produce a mix of the consistency herein specified, shall be added to the cement and aggregates before one quarter of the mixing time has elapsed. The size of the batch shall not exceed the maximum rated capacity as specified by the manu- facturer of the mixer. The drum shall be completely emptied before receiving material for the succeeding batch, Subdivision.Specifications Page 23 (b) Truck mixers if used, shall be of the revolving drum type. When a truck mixer is used for mixing the concrete, the drum shall be rotated at mixing speed for not less than fifty nor more than one - hundred revolutions after all of the ingredients of each batch are - placed in the drum. When a truck mixer is used for the complete mix- ing of the concrete, the mixing operation shall begin within thirty minutes after the cement has been intermingled with the aggregates. The size of the batch shall not exceed the manufacturer's rated capa- city as shown on a metal rating plate which shall be attached in a prominent place on the truck mixer. The drum shall be completely emptied before receiving material for the succeeding batch. (c) The mixing time at stationary batch mixers may be reduced to the minimum required (about thirty seconds) to intermingle the in- gredients when truck mixtures are used to deliver the mix to the site of the work. When this practice is followed each batch shall be thoroughly mixed in the truck mixer by rotating the drum at mixing speed for not less than fifty nor more than one hundred revolutions. (d) If manual mixing is authorized by the engineer, the cement and aggregates shall be mixed dry on a water tight platform until the mixture is of uniform color. The full amount of water required shall then be added and the mixing continued until the mass is of the con- sistency herein specified. 2. Consistency: The aggregates, cement and water shall be thoroughly mixed in accordance with these specifications to produce a homogenous mass which can be deposited in the forms without separa- tion. The consistency of the mix shall be such that the slump shall not exceed three inches. 3. Delivery; Concrete shall be delivered to the site of the work with a satisfactory degree of uniformity at the consistency specified and shall be hauled in a water tight container in which segregation will not take place and from which the concrete can be discharged freely. (a) Concrete shall be delivered to the site of the work and discharged from the hauling container within a period of ninety minutes after the introduction of the mixing water to the dry materi- als unless otherwise specified by the engineer. (b) Slump tests of individual samples taken at approximately the one - quarter and three - quarters points of the load during discharge shall not differ by more than two inches. 4. Retemperingr The retempering of mortar or concrete which has partially hardened with or without additional materials or water, is prohibited. Subdivision Specifications Page 24 V. FOUNDATION: 1. Sub - grade: The finished sub -grade shall have a transverse slope of not more than one -half inch per foot and shall be prepared as follows: (a) All soft and spongy places shall be removed and all depressions filled with suitable material which shall be thoroughly compacted in layers not exceeding six inches in thickness. (b) When the concrete sidewalk is to be constructed over an old path composed of gravel or cinders, the old path shall be entirely loosened, the material spread for the full width of the sub -grade and thoroughly compacted. (c) All fills shall be made in a manner satisfactory to the engineer. The use of muck, quicksand, soft clay, spongy or perishable material is prohibited. The top of all fills shall extend beyond the walk on each side for at least one-foot, and the sides shall have a slope of at least one or one and one -half to one. 2. Drainage: Suitable drainage systems shall be installed and connected with sewers or other drains as indicated on the plans. 3. Sub -base: A sub -base may be required by the engineer, if, in his opinion, the soil in the sub -grade will swell or shrink with changes in its moisture content to such an extent that the concrete may be damaged. If a sub -base is required, it shall consist of material as hereinbefore specified, and shall be spread to a depth of at least four inches, and thoroughly compacted. When a sub -base is spread on fills, the side slope of the sub -base shall be the same as the side slope of the fill. While compacting the sub -base the material shall be thoroughly wet, and shall be wet when the concrete is deposited but shall show no pools of water. VI`.. DIMENSIONS: 1. Size of slabs: The slabs shall have an area of not more than one hundred square feet. Length of slab shall be equal to the width. 2. Thickness of Walk: Minimum thickness shall be four inches. At driveway openings to dwellings, the minimum thickness of the walk shall not be less than six inches. The minimum thickness of driveway openings to alleys and commercial and industrial establishments shall be not less than eight inches. VII. FOEMS: 1. Materials: Forms shall be free from warp and of sufficient strength to resist springing out of shape. All wood forms shall be thoroughly wetted and metal forms oiled or coated with soft soap or whitewash before depositing any material against them. All mortar and dirt shall be removed from the forms that have been previously used. Subdivision Specifications Page 25 2. Setting: The forms shall be well staked or otherwise held to the established lines and grades and their upper edges shall conform to the established grade of the walk and shall be so aligned as to provide a transverse slope toward the curb of one - quarter inch per foot unless otherwise directed by the engineer. VIII. JOINTS: 1. Contraction Joints: Contraction joints shall be constructed at right angles to the center line of the sidewalk; the grooves shall extend to one - fourth the depth of the sidewalk. They shall not be less than one - eighth inch or more than one - fourth inch in width and shall be edged with an edging tool having a one - fourth inch radius. No slab shall be longer than the width of the sidewalk nor less than four feet unless otherwise directed by the Village Engineer. IX. DEPOSITING CONCRETE: 1. Continuous Pouring: After mixing, the concrete shall be handled rapidly and the successive batches deposited in a continuous operation until individual sections are completed. Under no circum- stances shall concrete that has partly hardened be used. The forms shall be filled and the concrete brought to the established grade. 2. Cold Weather Pouring: Concrete shall not be deposited when it appears likely that the air temperature may fall below 40 degrees F. during the pouring or within the following 24 hours unless preparations are made and precautions taken to prevent any damage to the concrete resulting from the low temperature. When placing concrete in cold weather, the contractor shall plan and prosecute his work in a manner which will assure satisfactory results. Any concrete damaged by freezing shall be removed and replaced by the contractor at his own expense. Concrete when deposited in the forms shall have a temperature of not less than 55 degrees F. nor more than 100 degrees F. The concrete shall be maintained at not less than the minimum temperature of 55 degrees F. for at least seventy -two hours after placing, or longer if necessary, until the concrete has thoroughly hardened. Concrete shall not be deposited on a frozen foundation. X. FINISHING: 1. Method: After the concrete has been brought to the established grade by means of a strike - board, it shall be worked with a steel trowel or wood float to give it a smooth, medium rough, or rough surface, as directed by the engineer. In no case shall dry cement or a mixture of dry cement and sand be sprinkled on the surface to absorb moisture or to hasten hardening. The type of finished surface re- quired by the engineer shall be prepared as follows: (a) Smooth Surface: The surface of the concrete shall be troweled with a steel trowel to a smooth, even surface free from depressions or irregularities of any kind. Excessive working of the surface with the trowel shall be avoided. Subdivision Specifications Page 26 (b) Medium Rough Surface: The surface shall be floated with a wooden float only, producing an even gritty finish. On wide sidewalks the finishing may be done with two applications of a canvas belt, not less than six inches wide, and two feet longer than the width of the sidewalk. For the first application, the belt shall be drawn across the surface with vigorous strokes at least twelve inches long, and moved ahead very slightly with each stroke. The second application shall be given immediately after the water glaze or sheen disappears. The stroke of the belt shall be not more than four inches, but the longitudinal motion shall be greater than during the first application. (c) Rough Surface: The surface shall be floated with a wooden float leveling all sags and producing an even surface. After being floated in this manner the roughening shall be done by slapping the surface of the concrete with the face of the float. The float shall be raised vertically from the concrete after each stroke. 2. Edges: Unless protected by metal, the surface edges of all slabs shall be rounded to a radius of one -half inch. The edges of all slabs which act as curbing shall be rounded to a radius of one and one -half inch. 3. Name Stamp: The contractor shall mark in the walk at each end of every one hundred and fifty feet of walk or fraction thereof, either by stamping or by inlaying an approved metal plate, his name and year in which the walk is constructed. The stamped letters shall be one inch high and one - fourth inch deep. If a metal plate is used, the top of the plate shall be flush with the top of the walk. XI. CURING AND PROTECTION: 1. Method: As soon as the concrete has hardened sufficiently to prevent damage, the finished surface shall be sprinkled with water or covered with sand or earth and, in either case, kept wet for at least three days. When authorized by the engineer, a chemical curing agent may be used, provided it is applied in accordance with the manufacturer's specifications. When high early strength cement is used, the minimum curing period shall be reduced to forty -eight hours. The freshly finished surface shall be protected from hot sun and drying winds until it can be sprinkled or covered as above specified. The concrete surface must not be damaged or pitted by rain. The contractor shall provide and use, when necessary, sufficient tarpau- lins to completely cover all sections that have been placed within the preceding twelve hours. The contractor shall erect and maintain suitable barriers to protect the finished surface. Any section damag- ed from traffic or other causes occurring prior to its official accep- tance, shall be repaired or replaced by the contractor at his own ex- pense in a manner satisfactory to the engineer. The covering shall be removed and disposed of by the contractor and the sidewalk back - filled to a minimum of one foot on each side before the work is officially accepted by the engineer. XII. TESTING: 1. The engineer may at his discretion, require the contractor to submit representative samples of the materials he proposes to use Subdivision Specifications Page 27. prior to delivery of the materials to the site of the work, and may, during the progress of construction, take samples and make tests to assure that the work is being performed in accordance with these specifications. The contractor shall co- operate in the making of such tests to the extent of allowing free access to the work, for the selection of samples. 2. All tests and samples shall be paid for by the contractor. 9.207 Alleys.) Where required, alleys shall be provided with a right of way of twenty feet and a paved surface of sixteen feet. This pavement shall be the equivalent of eight inches of gravel or crushed stone and shall be held in place by metal or treated wood curbs. 9.208 Pipeline Trench Construction.) The general conditions are a part of this specification and the Contractor is to consult them for instructions pertaining to the work under this heading. Work Included: The work to be done under this specification shall inc u e e furnishing of all implements, machinery, equipment, materials, and labor necessary to excavate and backfill trenches for water mains, storm sewers, sanitary sewers, force mains, and appurt- enances, and to restore original ground surfaces. Excavation: The trench shall be excavated so that the elevation of the inis ed line will be at the depth and grade shown on the plans with allowance for bedding as hereinafter specified. Unless otherwise indicated, all water mains and force mains shall be laid so that the minimum cover over the top of the pipe will be 5 feet. The width of the trench at the top of the pipe shall not be greater than 2.2 feet for 4 -inch through 12 -inch pipe, 3 feet for 14 -inch through 18 -inch pipe, 32 feet for 20 -inch through 24 -inch pipe, 4 ft. for 27 -inch and 30 -inch pipe and one and one -third times the outside diameter of the pipe for sizes greater than 30 inches. In the event that the Contractor varies or requests to vary from these limitations the Engineer will determine the construction procedure and materials which will be required of the Contractor to prevent overstressing the pipe. Where firm foundation is not encountered at the bottom of the excavation, due to soft, spongy or other unsuitable soil, the Con- tractor shall remove all such unstable material and replace as required under BEDDING OF PIPE. All excavated material not needed on the work shall be disposed of by the Contractor at locations outside the limits of the improvement unless otherwise directed by the Engineer. The Contractor shall not dispose of surplus excavated material on corporate or private property without first securing written permission from the Owner or Agent of the property. The Contractor shall do all pumping and bailing, well pointing, build all drains, and do all other work necessary to keep the trench- es clear of water. No claim for an amount of money in excess of the contract price for the work will be considered or allowed because of the character of Subdivision Specifications Page 28. the ground in which any trench or other excavation is made and /or when special foundation material is required. The Contractor shall assume the risk of meeting water, quicksand, hard pan, boulders, clay, rubbish, unforeseen obstacles, pavements, etc. Sidewalks shall not be obstructed and the Contractor shall make provision, where necessary, for the free passage of pedestrians. Hydrants shall not be buried, and shall at all times be maintained fully accessible to fire department personnel. Sheeting and Bracing: The Contractor shall furnish and put in place such braces, sheeting, etc., as may be necessary for the protec- tion of the workmen, the work, the public safety, and adjacent struc- tures, pipes, conduits or other improvements. Sheeting and bracing may be removed after the backfilling has -been completed or filled to an elevation to prevent caving of the sides of the excavation. All voids and holes left by the sheeting after being removed shall be carefully filled with fine sand and thoroughly com- pacted by special tools or puddling. The contract price shall be understood to include the cost for all sheeting and bracing that may be necessary to insure safe perform- ance of the work until the backfilling is complete. Underground Utilities: The information presented on the plans showing the approxima a location of private and /or public underground utility lines is of an approximate nature only and is included for the information of the Contractor. Information was obtained from available existing records and the Engineers shall not be held- - responsible for underground utilities whose location does not corre- spond with the information on the plans. Prior to starting construc- tion, the Contractor shall request all public or private agencies,to establish the field location of their underground utilities. The Contractor shall make such exploration as is necessary to determine the exact location of all underground utilities, and shall exercise sufficient care during the progress of work in the area to prevent damage to the utilities. Whenever, in the progress of the work, it becomes necessary to relocate any underground gas mains, telephone conduit or electrical lines, it shall be the responsibility of the utility company involved to make such relocation. It is the Contractor's responsibility to properly notify each utility agency in sufficient time so as to avoid interference with the progress of the work. Where it is necessary for the Contractor to relocate water or other pipes or conduits in direct conflict with the proposed pipe (exclu- sive of culverts) for which no public utility is responsible, in order for the work to proceed, and such relocation is not called for on the plans, the Contractor shall be allowed an extra, the amount of which shall be negotiated before the work is commenced. All existing underground utility pipes, conduits or cables shall be carefully supported and protected until the new pipeline is laid and M� Subdivision Specifications Page 29. the backfilling finished, or until the proper utility agency removes or changes them. Any damage done to such existing pipes, conduits or cables shall be immediately repaired or the damaged parts replaced by the Contractor. It shall be the Contractor's responsibility to noti- fy each and all persons, firms or corporations using or.responsible for any private or public underground utility pipes, conduits, cables and related structures, of the time or times he shall be working in the area of their facilities. Bedding of Pipe: The Contractor shall bed the lower quadrant of the pipe on a layer of gravel or crushed stone. Gravel or crushed stone shall pass a 3/4 inch sieve, and shall have a minimum thickness of 4 inches under the pipe barrel and 2 inches under bells, and shall be carefully placed and compacted around the pipe to provide uniform support to the bottom quadrant. If, in the excavation of the trench, the excavation has been made deeper than necessary, bedding material as specified above shall be used to fill the trench to the required grade. Backfilling: After the pipe is laid the Contractor shall immed- iately re-fill the trench, except that in trenches for pipe requiring pressure testing, pipe joints shall remain exposed until completion of pressure testing. Backfill around the sides to the top of the pipe shall be carefully deposited and thoroughly compacted by hand tamping in 6 -inch layers (loose measure). Backfill shall then be carefully placed to a level of 12 inches over the top of pipe. Only selected material which is free of large stones, clods, roots, etc., shall be used for this purpose. After the pipe has been covered as described above, the remaining depth of the trench shall be back - filled and compacted using excavated material unless such material is determined by the Engineer to be unsuitable. Unsuitable excavated material shall be removed from the area by the Contractor and dis- posed of as stated under EXCAVATION, and shall be replaced with suitable backfill material. No additional compensation will be allow- ed for such removal and replacement of unsuitable material. All backfill material shall be deposited in the trench in a manner such as not to damage the pipe or disturb its grade or alignment. The surface of the backfill shall be left smooth, sufficiently crowned to allow for settlement. Any trenches in which settlement occurs during the period of con- struction and within one year of the date of acceptance of the project shall be brought back up to the surrounding grade, and the surfaces restored as required under the appropriate sections of this specification. Special Backfill: Wherever the excavation is in streets, parking areas, driveways, or other paved areas, the trench shall be back - filled from the bottom to within 12 inches of the surface with gravel, crushed stone, or other approved granular backfill material, jetted for compaction. All surplus excavated material shall be removed from the area and disposed of by the Contractor, as stated under EXCAVA- TION. Subdivision Specifications Page 30. The top 12 inches of the trenches in streets, parking areas, drive- ways, or other paved areas shall be filled with approved road gravel or crushed stone as a temporary pavement, and shall be maintained level with adjoining pavement surfaces until the original type of pavement (or equal) is replaced. Removal of Existing Pavement Surfaces: The Contractor shall remove an lspose or all existing pavement surface materials as necessary to complete the pipeline trench construction. All existing Portland Cement concrete street and driveway pavements, including surfaces, bases and stabilized sub - bases, curbs and gutters, and sidewalks shall be removed to a width of not less than one foot on undisturbed ground on each side of the trench excavation. A saw cut to a minimum depth of 12 inches shall be made with a concrete sawing machine to provide a straight line joint between the existing pavement, curb and gutter or sidewalk which will remain and the portion to be removed and replaced. All debris from this work shall be removed from the area and disposed of as stated under EXCAVATION. No pieces of broken pavement, curb and gutter or sidewalk shall be deposited and buried in the backfilling of the trench excavation. Replacement of Pavement Surfaces: The Contractor shall reconstruct all street and-driveway pavements including surfaces, bases and stabilized sub - bases, curbs, and gutters, and sidewalks as required for the complete replacement of existing pavement surfaces which were removed for pipeline trench construction or which were damaged or destroyed by the Contractor's operations outside of the limits of the trench excavation. This work shall not be started until the trenches have been properly backfilled and thoroughly compacted as stated under SPECIAL BACKFILL, and all manholes, valve vaults, inlets, service boxes and other similar structures and appurtenances have been set to the established ground surface grade. The work shall be constructed in accordance with applicable provisions of and the most recent amendments to the "Standard Specifications for Road and Bridge Construction ", adopted August 1, 19689 by the State of Illinois, Division of Highways. Where the original surface was gravel, crushed stone, or cinder materials, the temporary pavement as required under SPECIAL BACKFILL shall be reshaped to proper grade and condition equal to or better than the original surface in accordance with Section 307 of the State Specifications. Replacement of all other pavement surfaces shall be in accordance, with the following paragraphs. Grade, cross - section and thickness shall match the existing adjoining pavement, except that thickness shall not be less than specified hereinafter. The temporary gravel pavement as required under SPECIAL BACKFILL shall be prepared as a base or sub -base for the new pavement in accordance with Section 307 of the State Specifications.
