Acceptance will be based on lots in accordance with 401.07. The lots will be divided into sublots of 1600 m
² (2000 sq yd) each for the pavement and shoulders. Each lot shall have a minimum of one sublot. The target density shall be determined from a test strip constructed in accordance with ITM 577. The target density shall be not less than 96.0 percent of the unit weight of the mixture at the optimum binder content at Ndes determined from the mix design. A separate test strip will be required on each course placed on the pavement and each course placed on the shoulder. The Engineer may determine the uniformity of compaction by taking cores. An additional test strip may be requested by the Contractor or Engineer.SECTION 401, BEGIN LINE 453, INSERT AS FOLLOWS:
SECTION 401, AFTER LINE 607, INSERT AS FOLLOWS:
The gradation complies with 401.05 with the allowable tolerance limits shown in 401.09.
The range for the binder content and gradation do not exceed the limits shown in 401.09.
The coarse aggregate angularity and binder content is within the limits shown in 904.02(c) and 401.05.
If the mixture is not in accordance with these requirements, adjustment points will be assessed in accordance with 401.09 for variations exceeding the requirements shown above.
