    • Abstract:
      "The Mechanistic Empirical Pavement Design Guide (MEPDG) and the

      subsequent AASHTO product DARWin-ME are signifi cant advancements in

      pavement design. However, they are substantially more complex than the

      1993 AASHTO Guide, which is currently used in many states. The new systems

      require signifi cantly more inputs from designers. Among them are many

      parameters with which today’s pavement designers are not familiar. In addition,

      MEPDG/DARWin-ME provides methodologies for the analysis and performance

      prediction of diff erent types of fl exible and rigid pavements for specifi c climatic

      and traffi c conditions. However, the models were developed using available

      Long Term Pavement Performance (LTPP) national wide data sets. These models

      require local calibration before MEPDG can be used by highway agencies

      effi ciently. Therefore, many data sets need to be pre-processed before their use

      for MEPDG/DARWin-ME. This process needs to be automated and assisted with
