This report proposes revisions to the "Mechanistic-Empirical Pavement Design Guide" (MEPDG) and software to (1) incorporate three alternative rut-depth prediction models that rely on repeated load (triaxial) permanent deformation or constant height testing to provide the requisite input data, and (2) provide revised coefficients for the original and alternative rut-depth transfer functions or prediction models derived from material properties measured in the laboratory and pavement performance data. Thus, the report will be of immediate interest to engineers in public- and private-sector organizations with responsibility for the structural design and analysis of asphalt concrete pavements.
