This guide is a powerful tool for the design of new and rehabilitation of pavement structures that provides engineers with a set of different models to predict future performance of the pavements.  In particular, major contributors to the behavior and durability of the pavement such as climate, traffic, and materials characteristics, are integrated in a set of empirical models to obtain a precise outline of performance and durability of pavements.  The potential benefits of using the MEPDG are to provide engineers and contractors with advanced tools, improvements in conservation, management, and conditions for users, and significant economic savings.  Recently, the WisDOT contracted with the University of Wisconsin-Madison to begin collecting property information to support the use of this guide for rigid pavements.


Higher quality in the construction of roads and highways has motivated the Wisconsin Department of Transportation (WisDOT) to move toward implementation of the new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG).


  1. Installing the MEPDG software (available from FHWA) for use within the University
  2. Exercise this software to identify all the required property and data inputs
  3. Make an initial assessment of the most sensitive inputs
  4. Document findings
