• Abstract:
  North Dakota currently designs roads based on the AASHTO Design Guide procedure, which is based on
  
  the empirical findings of the AASHTO Road Test of the late 1950s. However, limitations of the current
  
  empirical approach have prompted AASHTO to move toward the new mechanistically based pavement
  
  design procedure described in the Mechanistic Empirical Pavement Design Guide (MEPDG), which was
  
  released to the public for review in 2004 under NCHRP Project 1-37A. MEPDG combines mechanistic
  
  and empirical methodology and provides more realistic characterization of in-service pavements. Its
  
  mechanistic approach is both more thorough and more computationally complex than the existing
  
  AASHTO design method, and as a result the method can require an extensive number of detailed
  
  material, foundational, traffic, and environmental inputs. This and other factors can present a challenge to
  
  agencies wishing to implement the new method.
  
  Because AASHTO has adopted the MEPDG and highway agencies across the nation are moving towards
  
  its implementation, it is critical that North Dakota becomes familiar with the MEPDG documentation and
  
  software and identify input data requirements for design. This report summarizes the findings of MEPDG
  
  implementation in North Dakota, identifies input data needs and research steps of the MEPDG
  
  implementation in the state and also prepares North Dakota for successful implementation of the MEPDG
  
  statewide.
