k� When the final structural course is to be opened to traffic and the design speed is 55 mph or greater, if any defect is 3 /8 inch or greater, the Engineer may require deficiencies to be corrected within 72 hours after opening to traffic . For bicycle paths , 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 . Address all deficiencies in excess of 5/ 16 inch in accordance with 33042 . 5 . 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 . 33042 .4 . 5 .5 Friction Course Layer : Straightedge the friction course layer in accordance with 330- 12 . 4 . 2 , either behind the final roller of the paving train or as a separate operation upon completion of all paving operations . Notify the Engineer of the location and time of straightedge testing a minimum of 48 hours before beginning testing . The Engineer will verify the straightedge testing by observing the Quality Control straightedging operations . Address all deficiencies in excess of 3 / 16 inch in accordance with 330 - 12 . 5 . For laser acceptance , corrections may be made either before or after laser acceptance testing . 330- 12 .4 . 6 Acceptance : 33042 .4. 6. 1 Straightedge Acceptance : For areas of roadways where the design speed is less than 55 miles per hour, acceptance for pavement smoothness of the friction course will be based on verified Quality Control measurements using the straightedge as required by 330- 12 . 4 . 5 . The Engineer will verify the straightedge testing by observing the Quality Control straightedging operations . 33042 .4 .6 .2 Laser Acceptance . For areas of high speed roadways where the design speed is equal to or greater than 55 miles per hour, acceptance testing for pavement smoothness of the friction course (for mainline traffic lanes only) will be based on the Laser Profiler. Ramps , acceleration and deceleration lanes , and other areas not suitable for testing with the Laser Profiler will be tested and accepted with the straightedge in accordance with 330 - 12 . 4 . 5 . 5 and 330- 12 . 4 . 6 . 1 . The pavement smoothness of each lane will be determined by a Laser Profiler furnished and operated by the Department in accordance with FM 5 - 549 and a report issued with the Ride Number (RN) reported to one decimal place . If corrections are made , as required following Laser Acceptance , the pavement will not be retested for smoothness using the Laser Profiler. For this testing, the pavement will be divided into 0 . 1 mile segments . Partial segments equal to or greater than 0 . 01 mile will be considered as a 0 . 1 mile segment. The pavement will be accepted as follows : 1 ) For segments with a RN greater than or equal to 4 . 0 , the pavement will be accepted at full pay. 2) For segments with a RN less than 4 . 0 , the Engineer will further evaluate the data in 0 . 01 mile intervals for both wheel paths . If the RN is 3 . 5 or above for all 0 . 01 mile intervals in both wheel paths , the segment will be accepted at full payment . If the RN is less than 3 . 5 for one or more 0 . 01 mile intervals , the segment will be tested with the rolling straightedge in both wheel paths in accordance with FM 5 - 509 . If approved by the Engineer, this straightedging may be completed (in both wheel paths) as part of the Quality Control straightedging operations described in 330 . 12 . 4 . 5 . 5 , prior to testing with the laser profiler. Notify the Engineer of the location and time of - 79 - FPID ( S ) : 423186- 1 - 58 - 01 r
