• Abstract:
  A comprehensive and reliable database capable of storing variables of flexible pavements is required for local calibration and effective statewide implementation of the Mechanistic Empirical Pavement Design Guide (MEPDG) in New Mexico. In this study, such a database (called MEPDG database) has been designed and populated with data including material properties, pavement structural characteristics, traffic, climatic conditions, and performance data from existing NMDOT databases and other formats. Using the database, MEPDG was calibrated to represent the local materials and pavement conditions of New Mexico. A set of calibration coefficients have been recommended for designing NMDOT pavements and allow for level 2 MEPDG analysis. In addition, advanced statistical analyses such as parametric and nonparametric regressions were performed to rank New Mexico pavement design inputs as high-to-moderate-to-low sensitive to pavement performance.
