Portland Cement Concrete Pavement

420.12 Surface Tests. The surface of the finished pavement shall be tested and be within the tolerances specified in Article 407.09 and as follows:

Testing with a profilograph for the first several days of paving following initial start up or after a long shutdown period shall be performed as soon as the concrete has cured sufficiently to permit the testing.

When the average profile index for the entire project length does not exceed 67 mm/km (4.25 inch/mile), and no 160 m (0.1 mile) section has a profile index exceeding 160 mm/km (10 inches/mile), the contract unit price shall be increased according to the following Price Adjustment Schedule. When the profile index for a 160 m (0.1 mile) section does not exceed 160 mm/km (10 inches/mile) payment will be made at the contract unit price for that section. When the profile index for a 160 m (0.1 mile) section exceeds 160 mm/km (10 inches/mile) but does not exceed 235 mm/km (15 inches/mile) the contract unit price for that section will be reduced according to the following Price Adjustment Schedule.
