He shall also provide a longitudinal float of an approved design. 00360-4 The Contractor shall furnish a canvas or canvas -rubber composition belt for finishing the pavement, not less than 6-inches nor more than 10- inches wide, and at least 2-feet longer than the width of the pavement. A burlap finish is also allowed. The Contractor shall furnish and maintain at least two standard 10-feet steel or aluminum straight -edges. The Contractor shall furnish a sufficient number of bridges equipped to ride on the forms and span the pavement for finishing operations and for the installation and finishing of joints and center strips. All necessary finishing and edging tools shall be furnished as may be required to complete the pavement in accordance with the drawings. 360.5 Slip Form Paver. In the event the Contractor is permitted to use a slip form paving machine, all equipment and techniques used must be first approved by the City Engineer prior to any such operations. In the event a slip form paver is disapproved, then the equipment specified elsewhere in this item shall be used. The approval process shall take place after bids are received. A Clary screed, as approved by the City Engineer, may be used in lieu of a mechanical bull float and oscillating screed, as long as the Contractor can show that it will not ride over the concrete. Hand vibrators are required at the jobsite, when pouring concrete. A hand vibrator shall be used around all load transfer devices. 360.6 Subgrade and Forms. The subgrade shall be excavated as required, all unstable or otherwise objectionable material removed, and all holes, ruts, and depressions filled with approved material, as per Item 205 "Subgrade". Rolling and sprinkling shall be performed when, and to the extent directed, and the roadbed shall be completed to or above the drawings of the typical sections shown on plans and the lines and grades established by the Engineer. Material excavated in the preparation of the subgrade shall be utilized in the construction of adjacent shoulders and slopes, and any additional material required for the completion of the sections shall be secured from sources indicated on plans or designated by the Engineer. Drainage of the roadbed shall be maintained at all times. The subgrade shall be finished to the exact section of the bottom of the pavement as shown on plans, and tested with the approved.template operated and maintained by the Contractor. The subgrade shall be maintained in a smooth, compacted condition, in conformity with the required section and established grade until the pavement is placed, and shall be kept thoroughly wetted down sufficiently in advance of placing any pavement to insure its being in a firm and moist condition for at least 2 inches below the prepared surface. Sufficient subgrade shall always be prepared in advance to insure satisfactory prosecution of the work. No equipment or hauling shall be permitted on the prepared subgrade, except on special permission of the Engineer, which will be granted only in exceptional cases and only where a suitable protection in the form of two-ply timber mats or other approved material is provided. The subgrade under the forms shall be firm and cut true to grade so that each form section when placed will be firmly in contact for its whole length and base width, and exactly at the established grade. Any subgrade under the forms below established grade shall be corrected, using suitable material, placed, sprinkled and rolled as directed. Forms shall be staked with at least three pins for each ten -foot section. A pin shall be placed at each side of every joint. Form sections shall be tightly joined and keyed to prevent relative displacement. Forms shall be cleaned and oiled each time they are used. Forms shall be set for a sufficient distance in advance of the point where concrete is being placed to permit a finished and approved subgrade length of not less than 300 feet ahead of concrete placement, or as approved by the Engineers. Conformity of the grade and alignment of forms shall be checked immediately prior to placing concrete, and all necessary corrections made by 00360-5 the Contractor. Where any form has been disturbed or any subgrade becomes unstable, the form shall be reset and rechecked. In exceptional cases, the Engineer may require suitable stakes driven to the grade of the bottom of the forms to afford additional support. Sufficient stability of forms to support the equipment operated thereon and to withstand its vibration without springing or settlement shall be required. If forms settle over one -eighth (1/8) inch under finishing operation, paving operations shall be stopped and the forms shall be reset to line and grade. Forms shall remain in place for not less than 8 hours after the concrete has been placed. They shall be carefully removed in such a manner that little or no damage will be done to the edge of the pavement. Any damage resulting from this operation shall be immediately repaired. After the forms have been removed, the ends of all joints shall be cleaned, and any honeycombed areas pointed up with approved mortar. Immediately after pointing is complete, the form trench shall be filled with earth from the shoulders in such manner as to shed water from rainfall or curing away from the edge of the pavement. On completion of the required curing, the subgrade or shoulders adjacent to the pavement shall be placed in condition to maintain drainage. 360.7 Reinforcing Steel and Joint Assemblies. All reinforcing steel, tie bars and load transmission units used in accordance with plan provisions shall be accurately placed and secured in position in accordance with details shown on drawings. Reinforcing bars shall be securely wired together at all intersections and splices, and shall be accurately wired to each dowel and load transmission unit intersected. The tie bars shall be installed in required position by the method and device shown on drawings, or by approved method and device equivalent thereto. Bar coatings required by plans, and of material specified, shall be completed and the bars and coating shall be free of rust, dirt or other foreign matter at the time of installation in the concrete. Reinforced steel to be supported on bar chairs or other approved devices placed on maximum 36" centers each way. Where plans require an assembly of parts at pavement joints, the assembly shall be completed, placed at required location and elevation, and all parts rigidly secured in required position by the method and devices shown on plans, or by approved method and devices equivalent thereto. Dowel Bars shall be accurately installed in joint assemblies in accordance with drawings, each parallel to the pavement, and shall be rigidly secured in required position by such means (as shown on plans, or approved equivalent thereto) that will prevent their displacement during placing and finishing of the concrete. The assembled units comprising the load transmission devices shall be accurately installed in joint assemblies in accordance with plans, each unit vertical with its length perpendicular to the centerline of the pavement, and all units shall be rigidly secured in required position by such means (as shown on drawings, or approved equivalent thereof) that will prevent their displacement during placing and finishing of the concrete. Leader boards, joint filler and other material used for forming joints shall be accurately notched to receive each load transmission unit. All load transmission units shall be free of rust and clean when installed in the concrete. 360.8 Concrete Placing. No concrete shall be placed when the air temperature is at or below 350 F. The temperature of the concrete shall at no time fall below 60° F., or exceed 1000 F. When the concrete reaches a temperature of 850 F., retarders shall'be introduced into the mixture and shall continue to be used until the concrete reaches a temperature of 950 F. After 950 F. and through 1000 F., a plasticizer shall be introduced into the mixture. After 950, ice may be used to control temperature, in lieu of a plasticizer. For concrete between temperatures of 850 F. through 950 F., the slump shall be as specified in Item 360. For concrete with temperatures greater than 950 F., slumps shall be as specified by the Engineer. 00360-6 The amount of retarder or plasticizer, introduced into the mixture, shall be in accordance with the manufacturer's recommendations. See part 360.2, Materials, for requirements of admixtures. No concrete shall be used if the concrete has developed initial set, or which is not in place within 1-1/2 hours after the initial water has been added. Pouring concrete during inclement weather, which would adversely effect the quality and/or finish _ of the concrete pavement does not relieve the contractor from his responsibility to provide a pavement that complies with the specification. 360.9 Joints. All transverse and longitudinal joints in the pavement shall be of the type or the alternate type shown on the drawings, shall be constructed at required locations, on required alignment in the required relationship to tie bars and joint assemblies and in accordance with the details shown on the plans. Normally, the stoppage of the placement of concrete shall be scheduled to occur at proposed expansion joints, or at proposed longitudinal joints located between traffic lanes. If it becomes necessary to stop the placement of concrete at an unscheduled location due to unforeseen circumstances, the stoppage may occur at a proposed contraction joint, or at other locations with the approval of the Engineer. The following provisions shall govern for each type of joint at which the placing of concrete is stopped: When the placing of concrete is stopped at any expansion joint, the complete jointed assembly shall be installed and rigidly secured in required position as shown on plans. A bulkhead of sufficient cross sectional areas to prevent deflection, accurately notched to receive the load transmission units or dowels, as the case may be, and shaped accurately to the cross section of the pavement shall be provided and installed as a back-up for the joint filler and rigidly secured in required position to permit accurate finishing of the concrete up to the joint. After the concrete has been finished to the joint, formation of the joint seal space and finishing of the joint shall be executed as specified herein and in accordance with plan requirements. The back-up bulkhead shall remain in place until immediately prior to the time when concrete placing is resumed, when it shall then carefully be removed in such manner that no element of the joint assembly will be disturbed. The exposed portions of the joint assembly shall be free of adherent concrete, dirt or other material at the time placing of concrete is resumed. When placing of concrete is stopped at a longitudinal joint, all applicable provisions of Section 360.7 shall apply in addition to the following requirements: The face of the bulkhead at the joint shall be grooved or recessed as necessary to provide the required spaces for the top and bottom breaker strips as shown on plans. The bulkhead shall be either drilled or notched to receive the tie bars. Tie bars shall be secured in required position by use of adequate transverse bracing and vertical supports meeting the approval of the Engineer. When placing of concrete is stopped at a contraction joint, all applicable provisions of Section 360.7 shall apply, in addition to the following requirements: The face of the bulkhead adjoining the slab end shall be notched and grooved to fit the exposed half -screen of the joint assembly and shall be shaped to form the slab end at the center of joint as shown on plans. The half -width of joint seal -space may be formed by a strip of required section placed and removed in accordance with drawing requirements for construction of transverse contraction joints. The Contractor shall have available a bulkhead shaped to the section of the pavement, and of a section to form a key not less than 1 inch in depth and 2 inches in height at the center of depth of the pavement. This bulkhead must be drilled to permit the continuation of all longitudinal reinforcing steel through the construction joint, and shall be of sufficient section and strength to prevent deflection. 00360-7 Immediately upon the intended stoppage of the placing of concrete to a line, install the above described bulkhead at right angles to the centerline of the pavement perpendicular to the surfaces and at required elevation. Concrete shall be placed and finished to this bulkhead. Any concrete remaining on the subgrade ahead shall be removed and disposed of as directed. When placing of concrete is resumed before the concrete has set to the extent that the concrete will stand on removal of the bulkhead, the new concrete shall be rodded, and the key in the first concrete must be carefully preserved. An edge created by a construction joint of this type shall have a joint seal space and shall be sealed as required for construction joints. Transverse expansion joints shall be formed perpendicular to the centerline and surface of the pavement, and shall be constructed in accordance with the sequence of operations shown on drawings. After the transverse finishing machine and before the longitudinal finishing machine has passed over the joint, the contractor shall test the joint filler for correctness of position and make any required adjustment in position of the filler, and shall install the joint seal space form in accordance with plans. After removal at the joint seal form as required by plans, the joint seal space above the joint filler shall be thoroughly cleaned and the concrete faces of the joint seal space shall be left true to line and section throughout the entire length of the joint. On completion of curing of the pavement, the joint sealing filler of the type specified shall be placed in accordance with drawings. The faces of the joint seal space shall be clean and surface dry at the time joint sealing filler is placed. On completion of the joint seal, the pavement adjacent to the joint shall be left free of joint sealing material. 360.10 Finishing. All concrete pavement shall be tamped and finished mechanically with approved power driven machines, except as herein provided. Hand finishing will be permitted on the transition from a crowned section to a super -elevated section without crown on curves, and on straight-line super elevation sections less than 300-feet in length. Hand finishing will also be permitted on that portion of a widened pavement outside the normal pavement width, on sections where the pavement width is not uniform, or required monolithic widths are greater than that of available finishing machines. Machine finishing of pavement shall include the use of a power driven transverse strike -off, tamp and screed and a longitudinal float. The transverse finishing machine shall first be operated to compact and finish the pavement to the required section and grade, without surface voids. The machine shall be operated over each area as many times and at such intervals as directed. At least two trips will be required, and the last trip over a given area shall be a continuous run of not less than 40 feet. After completion of finishing with the transverse finishing machine, the longitudinal mechanical float shall be operated to smooth and finish the pavement to the required grade. The float shall be operated paralleled to the centerline of the pavement with a short, quick motion, and shall travel slowly across the pavement, maintaining contact with the surface at all points. If this result is not attained, additional concrete shall be placed if required, tamped and screeded, and the float shall operate over the same area until a satisfactory surface is produced. The advance along the length of the pavement between successive passes of the float across the surface shall be such that the float shall continuously lap its previous position by not less than one-fourth its length. After floating is complete, and the concrete still workable, the surface shall be tested for conformity with an approved 10-foot steel straightedge. The straight -edge shall be operated from the side of the pavement, placed paralleled to the pavement centerline and passes across the slab to reveal any high spots or depressions. The straightedge shall be advanced along the pavement in successive stages of not more than one-half its length. Any correction of the surface required shall be accomplished by adding concrete if required and by operating the longitudinal float over the area. The surface test with the straightedge shall then be repeated. 00360-8 After completion of the straight -edge testing, and just before the concrete becomes non -plastic, the surface shall be belted with an approved belt, operated with short transverse strokes and a rapid advance longitudinally. This operation shall produce a uniform surface of a gritty texture. About the time the concrete becomes hard, the edge of the slab shall be carefully finished with an edger of the radius required by the Engineer, and the pavement edge shall be left smooth and true to line. Hand finishing shall be resorted to only in those conditions provided for above, and upon specific authorization by the Engineer. When hand finishing is permitted, the concrete shall be struck off with an approved strike -off screed to such elevation that when consolidated and finished the surface of the pavement shall conform to the required section and grade. The strike template shall be moved forward with a combined transverse and longitudinal motion in the direction the work is progressing, maintaining a slight excess of material in front of the cutting edge. The concrete shall then be tamped with an approved tamping template to compact the concrete thoroughly, and eliminate surface voids, and the surface screeded to required section. After completion of a strike -off, consolidation, and transverse screeding, a hand -operated longitudinal float shall be operated to test and level the surface to the required grade. Workman shall operate the float from approved bridges riding on the forms and spanning the pavement. The longitudinal strokes while being passed from one side of the pavement to the other shall be continuous. If contact with the pavement is not made at all points, additional concrete shall be placed if required, tamped and screeded, and the float shall be used to produce a satisfactory surface. Care shall be exercised to keep the ends of the float from digging into the surface of the pavement. After a section has been smoothed so that the float maintains contact with the surface at all points in being passed from one side to the other, the bridges may be moved forward half the length of the float, and the operations repeated. Just before the concrete becomes non -plastic, texture shall be applied with tines, belts, or other methods approved by the Engineer. The texture shall be applied transversely. It is the intent that _. the average texture depth, resulting from the number of tests directed by the Engineer, be not less than 0.060-inch with a minimum texture depth of 0.050-inch for any test done in accordance with Test Method Tex-436- A. Should the texture depth fall below that intended, the finishing procedures shall be revised to produce the desired texture. After the concrete has been placed 12 hours or more, the Engineer will test the surface of the pavement with a ten -foot straight -edge placed parallel to the centerline. The straight edge shall be approved by the Engineer. The surface shall not vary from the straight edge by more than one -sixteenth (1/16) inch per foot from the nearest point of contact, and in no case shall the maximum ordinate from a ten -foot straight -edge to the pavement be greater than one -eighth (1/6) inch. Any high spots causing a departure from the straightedge in excess of that specified shall be ground down by the Contractor to meet the surface test requirements, when required by the Engineer. _ 360.11 Curing. The Contractor shall provide for protection of freshly laid concrete against pitting and washing from rain, by having on the job at the time and place of pouring, sufficient canvas and/or waterproof covering material to protect at least 400 linear feet of pavement over the entire width of pavement surface being placed. See the Item 421, "Structural Concrete", for additional -- information. 360.12 Protection of Pavement. The Contractor shall erect and maintain the barricades required by the plans, and such other barricades and approved devices as will exclude public traffic and traffic of his employees and agents from the newly placed pavement for the periods of time hereinafter prescribed. Portions of the roadway, or crossings of the roadbed required to be maintained open for use by traffic, shall not be obstructed by the above required barricades. Crossings of the pavement required by plans, or by construction sequence, during the period 00360-9 360.17 Acceptance Requirements. For pavement concrete, concrete mixes shall be formulated to produce concrete that meets the minimum flexural strength as shown in this item. If the required strength is not secured with the minimum cement content specified, additional cement shall be used or other aggregate provided at the Contractor's expense. 360.18 Measurement. Concrete pavement shall be measured by the square yard of the specified thickness of completed and accepted pavement. This shall include all necessary concrete headers, as shown on the plans. Separate measurement and payment will not be made for concrete headers. 360.19 Payment. The work performed and the materials fumished as prescribed by this item and measured as provided under "Measurement' shall be paid for at the unit price bid for "Concrete Pavement', or "Concrete Pavement, High Strength", as required, or the adjusted unit price for pavement of deficient thickness as provided under "Penalty for Deficient Pavement Thickness", which price shall be full compensation for shaping and fine grading the roadbed, including furnishing and applying all water required; for furnishing, loading and unloading, storing, handling all concrete ingredients, including all freight and royalty involved; for mixing, placing, finishing and curing all concrete; for furnishing all materials for and placing longitudinal, warping, expansion, sawed control and contraction joints, and load transmission units, and joint filler material in proper position; for coating steel bars where required by plans, for furnishing and placing all reinforcing steel; and for all manipulations, labor, equipment, appliances, tools, traffic provisions and incidentals necessary to complete the work. 00360-12
