., . ,..., r"I 330-12.4.5.3 Intermediate Layers: Straightedge all intermediate Type SP layers (structural and overbuild) as necessary to construct a smooth pavement. On roadways with a design speed 50 miles per hour [80 km per hour] or greater, when an intermediate Type SP layer will be opened to traffic, straightedge the pavement with a rolling straightedge and correct all deficiencies in excess of 3/8 inch [10 mm] within 72 hours of placement, unless directed otherwise by the Engineer. Correct all deficiencies in accordance with 330-12.5.1. 330-12.4.5.4 Final Type SP Structural Layer: Straightedge the final Type SP structural layer with a rolling straightedge, either behind the final roller of the paving train or as a separate operation. The Engineer will verify the straightedge testing by observing the Quality Control straightedging operations. Correct all deficiencies in excess of 3/16 inch [5 mm] in accordance with 330-12.5.1, and retest the corrected areas prior to placing the friction course. For bicycle paths, straightedge the final structural layer with a rolling straightedge, either behind the final roller of the paving train or as a separate operation. Correct all deficiencies in excess of 5/16 inch [8 mm] in accordance with 330- 12.5.1. Retest all corrected areas. If the Engineer determines that the deficiencies on the bicycle path are due to field geometrical conditions, the Engineer will waive corrections with no deduction to the pay item quantity. 330-12.4.5.5 Friction Course Layer: Acceptance for pavement smoothness will be based on verified Quality Control measurements using the rolling straightedge. The Engineer will verify the straightedge testing by observing the Quality Control straightedging operations. At the completion of all paving operations, straightedge the friction course as a separate operation. As an exception, if approved by the Engineer, straightedge the friction course behind the final roller of the paving train. Correct all deficiencies in excess of 3/16 inch [5 mm] in accordance with 330-12.5.1. Retest all corrected areas. 330-12.5 Correcting Unacceptable Pavement: 330-12.5.1 General: Correct all areas of unacceptable pavement at no cost to the Department. 330-12.5.1.1 Structural Layers: Correct deficiencies in the Type SP structural layer by one of the following methods: a. Remove and replace the full depth of the layer, extending a minimum of 50 feet [15 m] on either side of the defective area for the full width of the paving lane. b. Mill the pavement surface to a depth and width that is adequate to remove the deficiency. (This option only applies if the structural layer is not the final surface layer.) 330-12.5.1.2 Friction Course: Correct deficiencies in the friction course layer by removing and replacing the full depth of the layer, extending a minimum of 50 feet [15m] on either side of the defective area for the full width of the paving lane. Corrections may be waived if approved by the Engineer, and an adjustment to the pay item quantity made as defined in 330-12.5.2. 330-12.5.2 Reduction in Pay Item Quantity: When the Engineer elects to waive corrections, the Department will reduce the pay quantity for the pay item in question by the amount of material that the Contractor would have removed and replaced had the correction been made. When the pay quantity is in tons [metric tons], the Department will . ,., . " . " . '1 . " I . .., . I "1 . .., . .., . 1"'1 . '"" . .., . ..., . 1"1 . . .., 09/09 01000-50 03-4122.F -
