Pavement Roughness Evaluations Using a Mays Ride Meter

摘要

The report is concerned with the analysis of roughness data on new pavement construction and recent resurfacings and the development of an acceptance procedure for resurfacings. A high-speed measurement device known as the Mays Ride Meter was used for much of the roughness testing. The Mays meter consists of instrumentation mounted in a passenger car which measures smoothness in terms of the relative motion between the car body and axle. Smoothness tests performed on new freeways indicate that the overall rideability of our bituminous pavements has improved substantially, a 'Good' rating being typical. Rolling straightedge-based smoothness acceptance provisions have been adopted to deal with the isolated instances of unacceptable riding quality which continue to be observed. Data from several new concrete projects indicate a small, yet significant relative improvement in rideability.
