The new Mechanistic-Empirical Pavement Design Guide (MEPDG) developed under the National Cooperative Highway Research Program (NCHRP) Project 1-37A represents a major change as compared to the 1993 AASHTO Pavement Design Guide. The MEPDG provides a rational pavement design framework based on mechanistic-empirical principles to characterize the impacts of traffic, climate, and material properties on the pavement performance. Before replacing the 1993 Pavement Design Guide (and its accompanying DARWin 3.1 design software) currently used by Louisiana Department of Transportation and Development (LADOTD), the nationally calibrated MEPDG distress prediction models need to be further validated and calibrated against the local conditions in Louisiana. The objectives of this study were to use the MEPDG design software (version 1.1) to evaluate the performance of typical Louisiana flexible pavement types, materials, and structures as compared with the pavement performance data from the pavement management system (PMS) and identify the areas for further local calibration of the MEPDG in Louisiana. In this study, a total of 40 asphalt concrete (AC) pavement projects were strategically selected throughout Louisiana with different design traffic and subgrade properties.
