Development of a Flexible Pavement Database for Local Calibration of MEPG

The results of this research will enable the New Mexico Department of Transportation (NMDOT) to provide pavement design professionals with appropriate tools and a better understanding of how the new Mechanistic Empirical Pavement Design Guide (MEPDG) will allow for optimization of materials, evaluate and incorporate new materials into designs, and evaluate the impacts of anticipated heavier loads and new axle configurations on pavement performance in New Mexico. With the existing method, pavement life is not correlated with the mode of failure. MEPDG design methodology is expected to allow the NMDOT to establish the anticipated failure mode, and level of distress at the end of the design life (e.g. rutting, bottom-up cracking or top-down cracking), resulting in cost efficiency comparisons and optimizations
