• 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 ; software."
