Smoothness Measurement Sample Clauses

Smoothness Measurement. The Department will test the longitudinal profile of the final riding surface for ride quality with a Class 1 Inertial Profiling System according to AASHTO MP 11. The Department will not measure locations where the traffic striping includes turn lanes that cause the through traffic lane to cross over a longitudinally paved joint. Ramps and lanes such as acceleration and deceleration lanes of less than 1000′ of continuous through treatment will not be measured. If project conditions preclude the use of the Class 1 Inertial Profiling System, the Department will use a Class 1 walking profiler or lightweight profiler. The Department will test the full extent of each wheel path of each lane in the longitudinal direction of travel. The wheel path is defined as being located approximately 3 feet on each side of the centerline of the lane and extending for the full length of the lane. For the purposes of this specification, lanes are defined by striping. The IRI value reported for each lot is the average of 3 runs of each wheel path, unless otherwise directed by the Department.
