• AASHTOWARE® PAVEMENT ME DESIGN FOR FLEXIBLE PAVEMENT 2.1 Background The 1993 American Association of State Highway and Transportation Officials (AASHTO) Guide for Design of Pavement Structures (4) has been the primary procedure used to design new and rehabilitated flexible pavements (5). This empirical design procedure is based on the design.
• For the design of new jointed plain concrete pavements (JPCPs), three national calibrations of the AASHTOWare Pavement ME Design have been necessary due to model and database updates. Local calibration is also recommended to better match a state’s experience. To date, 8 states have changed the.

About the research. The Mechanistic-Empirical Pavement Design Guide (MEPDG) was developed under National Cooperative Highway Research Program (NCHRP) Project 1-37A as a novel mechanistic-empirical procedure for the analysis and design of pavements.

The Michigan Department of Transportation (MDOT) is currently working towards implementing the new AASHTOWare ME Pavement Design software. This site will provide progress reports as well as links to other ME-related resources.

ME Pavement Design is the latest generation of pavement design methodologies. It utilizes the theories of mechanics of materials to predict the pavement's response (stresses and strains) to load. The pavement's response is then correlated into damage, which is accumulated over the design life and results in predicted distresses over time. Climatic conditions (temperatures, moisture levels, etc.) are taken into account through the material properties of the constituent pavement layers. Finally, the models used to predict distresses are calibrated using observed distress amounts (the empirical portion of the name).
