• 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."
