The model uses detailed environmental data and can determine the optimal mixture design for specific conditions. The pavement performance models for each distress also were used to confirm the relevant binder and mixture properties established by other SHRP contractors using accelerated laboratory tests and laboratory torture tests; and to establish the degree of correlation between those asphalt binder and mixture properties. Results from these model studies were used to confirm or make recommendations for revisions to the asphalt binder specification.Researchers developed a model to predict the amount of fatigue cracking, thermal cracking, and rutting in asphalt concrete pavements over time, using results from the accelerated laboratory tests.
