This report presents mechanistic-based models for predicting the extent and severity of reflection cracking in hot-mix asphalt (HMA) overlays. These models were developed for use in the design and analysis of HMA overlays; they can be incorporated into the AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) software. The report and accompanying software will guide pavement and construction engineers in identifying and specifying HMA overlays for asphalt and concrete pavements that will provide desired service life and performance. The information contained in the report will be of immediate interest to state pavement engineers and others concerned with the design and rehabilitation of asphalt and concrete pavements.
