INTEGRATION OF INERTIAL PROFILOMETER IN ODOT PAVEMENT MANAGEMENT SYSTEM. FINAL REPORT

Pavement roughness and ride quality information, for the Ohio Department of Transportation (Ohio 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 Present Serviceability Rating (PSR) and PSR trigger values for non-routine maintenance. Pavement profiles measured with the Ohio DOT Inertial Profilometer have 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. Pavement profiles measured with the Ohio DOT Inertial Profilometer have also been used to compute expected overlay material quantities and pavement ride quality on an Ohio DOT demonstration resurfacing project.
