Canadian calibration on mechanistic - Empirical pavement design guide to estimate international roughness index (IRI) using MTO data

This paper presents flexible pavement performance models developed for the Ministry of Transportation of Ontario (MTO) by using data from the MTO's Pavement Management System (PMS2). The performance model coefficients have been developed for application in the Mechanistic - Empirical Pavement Design Guide (MEPDG) and were calibrated using statistical tools through a series of analyses on historical pavement condition data that was collected in …
