Use of the Inertial Profilometer in the Ohio DOT Pavement Management System

Pavement roughness and ride quality information, for the Ohio Department of Transportation (DOT) Pavement Management System, can be accurately computed directly from highway pavement profiles measured with the Ohio DOT inertial profilometer. The pavement ride quality information includes the present serviceability index (PSI) and PSI trigger values for nonroutine maintenance. Pavement profiles measured with the Ohio DOT inertial profilometer have also been used to calibrate the Ohio DOT Mays ride meter system, to analyze the Mays Ride meter system performance, and to provide a link between that system and pavement roughness and ride quality information obtained from the Ohio DOT inertial profilometer.
