§ 5.31 FINAL SURFACE FINISH.
   The final surface finish for the paving shall be a broom, artificial turf or burlap drag finish to meet the approval of the engineer.
§ 5.32 CURING METHODS.
   Provisions shall be made for maintaining concrete in a continuously moist condition for a period of at least seven days after placement of the concrete by means of curing compound, polyethylene film, waterproof paper or wet burlap.
§ 5.33 SAWING, CLEANING AND FILLING JOINTS.
   (A)   Whenever sawed joints are to be provided they are to be sawed with a machine made especially designed for sawing concrete. The saw cuts are to have a depth of one-fourths of the thickness of the paving slab and a minimum width of one-eighths inch. Such sawing shall be done as soon as possible but under no circumstances shall the time of such sawing exceed 24 hours after the placing of the concrete.
   (B)   Just prior to filling the sawed joints in hardened concrete, each joint shall be thoroughly cleaned of all foreign material to its full depth by means of compressed air at sufficient pressure to accomplish the result satisfactory to the engineer.
   (C)   Joints shall be filled in such a manner that the filler not be spilled on the surface of the concrete. Sufficient filler shall be inserted into the joints so that the filler is flush with the surface of the pavement when the work is completed. When filling joints on slopes and intersections, the work shall start at the lowest point and progress toward the highest point.
§ 5.34 BACKFILLING.
   After the forms have been removed, the contractor shall backfill and grade the area from the back of the curb to the property line with a one-half inch per foot incline from the level of the curb to the property line. The contractor shall not be paid for this portion of the excavation. It shall be included in the unit price for the pavement.
§ 5.35 FINAL CLEANING.
   After all construction is completed and prior to final acceptance, the concrete pavement shall be free of all foreign material. When necessary, the entire job or portions thereof shall be required to be broomed or cleaned to the approval of the engineer.
§ 5.36 DEFICIENT THICKNESS.
   (A)   Pavement slab thickness will be determined by at least two cores taken from each lane and at such other locations as the engineer may direct.
   (B)   (1)   Payment will not be made for slabs deficient in thickness by more than one-half inch. If so ordered by the engineer, such slabs shall be removed and replaced at the expense of the contractor with concrete of required thickness which when accepted shall be included in the pay yardage.
