An experimental design based evaluation of sensitivities of mechanistic - Empirical pavement design guide (MEPDG) predictions for Ontario's local calibration

A Mechanistic-Empirical Pavement Design Guide (MEPDG) was developed under NCHRP Project 1-37A to address the shortcomings of empirical pavement design methods. The MEPDG uses mechanistic-empirical models to analyze the impacts of traffic, climate, materials and pavement structure and to predict long term performances of pavement. The MEPDG software (AASHTOWare Pavement M-E) use a three-level hierarchical input scheme to predict pavement …
