29、his specification section is structured for Contractor sampling and testing of materials and mixture proportioning. If Government sampling, testing and mixture proportioning is required, contact the TSMCX, MAJCOM pavement engineers, or NAVFAC for specification language.*1.1 UNIT PRICES*NOTE: Any pro

30、ject large enough to use this guide specification should have Unit Price payment. For Lump Sum payment, include concrete unit price from Government estimate in paragraph Payments to provide cost basis for calculating payment reduction.*1.1.1 MeasurementsThe quantity of concrete to be paid for will b

31、e the volume of concrete in cubic meters yards including thickened edges monolithic curb, where required, placed in the completed and accepted pavement. Concrete will be measured in place in the completed and accepted pavement only within the neat line dimensions shown in the plan and cross section.

32、 No deductions will be made for rounded or beveled edges or the space occupied by pavement reinforcement, dowel bars, tie bars, or electrical conduits, nor for any void, or other structure extending into or through the pavement slab, measuring 0.1 cubic meter 3 cubic feet or less in volume. No other

33、 allowance for concrete will be made unless placed in specified locations in accordance with written instructions previously issued by the Contracting Officer. The quantity of other materials specified herein, and used in the construction of the work covered by this section, will not be measured for

34、 payment, but will be considered a subsidiary obligation of the Contractor, covered under the price per cubic meter yard for concrete. Joint sealing materials are covered in Section 32 01 19 FIELD MOLDED SEALANTS FOR SEALING JOINTS IN RIGID PAVEMENTS or Section 32 13 73 COMPRESSION JOINT SEALS FOR C

36、ed above will be paid for at the contract unit price when placed in completed and accepted pavements. Payment will be made at the contract price for cubic meter yard for the scheduled item, with necessary adjustments as specified below. Payment will constitute full compensation for furnishing all ma

37、terials, equipment, plant and tools, and for all labor and other incidentals necessary to complete the concrete pavement, except for other items specified herein for separate payment.1.1.2.2 Lump SumThe quantity of concrete will be paid for and included in the lump-sum contract price. If less than 1

38、00 percent payment is due based on the pay factors stipulated below, a unit price of _ per cubic meter yard will be used for purposes of calculating the payment reduction.1.1.3 Payment of LotsWhen a lot of material fails to meet the specification requirements, that lot will be accepted at a reduced

39、price or shall be removed and replaced. The lowest computed percent payment determined for any pavement characteristic (i.e., thickness, grade, and surface smoothness) discussed below shall be the actual percent payment for that lot. The actual percent payment will be applied to the unit price and t

40、he measured quantity of concrete in the lot to determine actual payment. Use results of strength tests to control concreting operations. Strength will be evaluated, but will not be considered for payment adjustment. Any pavement not meeting the required specified strength shall be removed and replac

When more than 5.0 and less than or equal to 10.0 percent of all measurements made within a lot exceed the toler

42、ance specified in paragraph “Surface Smoothness“, after any reduction of high spots or removal and replacement, the computed percent payment based on surface smoothness will be 95 percent. When more than 10.0 percent and less than or equal to 15.0 percent of all measurements exceed the tolerance, th

43、e computed percent payment will be 90 percent. When more than 15.0 and less than or equal to 20.0 percent of all measurements exceed the tolerance, the computed percent payment will be 75 percent. When more than 20.0 percent of the measurements exceed the tolerance, the lot shall be removed and repl

44、aced at no additional cost to the Government.b. Profilograph Testing: Location and data from all profilograph measurements shall be recorded. When the Profile Index of a 0.1 km 0.1 mile segment of a lot exceeds the tolerance specified in paragraph “Surface Smoothness“ by 16 mm per km 1.0 inch per mi

45、le but less than 32 mm per km 2.0 inches per mile, after any reduction of high spots or removal and replacement, the computed percent payment based on surface smoothness will be 95 percent. When the Profile Index exceeds the tolerance by 32 mm per km 2.0 inches per mile but less than 47 mm per km3.0 inches per mile, the computed percent payment will be 90 percent.
