Local Calibration of MEPDG - An Overview of Selected Studies (With Discussion)

The overall Mechanistic-Empirical Pavement Design Guide (MEPDG) objective is providing a state-of-the-practice tool for the highway community to use in new and rehabilitated flexible pavement structure design and analysis based on mechanistic-empirical (M-E) principles. This paper is designed to provide an overview of selected study results regarding local MEPDG validation-calibration and compares different study local calibration values. MEPDG sponsors and developers realized the importance of local validation and calibration needs, and, in order to adjust predicted distress values, incorporated local calibration parameters.
