• Abstract:
  This TechBrief summarizes an exploratory analysis of the AASHTOWare Pavement ME Design™ (PMED) software’s pavement performance predictions. The research team analyzed the sensitivity of PMED outputs to traffic input levels based on data from a sample of Long-Term Pavement Performance (LTPP) program sites. In this TechBrief, MEPDG refers to the method for analyzing and designing pavement structures described in the AASHTO’s Mechanistic–Empirical Pavement Design Guide, A Manual of Practice (MEPDG), while PMED refers specifically to the AASHTOWare Pavement ME Design™ software product that uses the MEPDG method.
