Abstract:To account for different variables related to traffic, climate and materials, and their interactions affecting pavement performance, a research effort initiated by the National Cooperative Highway Research Program (NCHRP) has led to the development of a Mechanistic-Empirical Pavement Design Guide. This guide is being adapted by the Wyoming Department of Transportation (WYDOT) for roadway designs. However, the default input variables recommended in the MEPDG were developed based on national conditions that do not reflect the local Wyoming conditions. Calibration procedures and methods are needed to calibrate the guide for use on the local level.
