Optimizing Laboratory Curing Conditions for Hot Mix Asphalt to Better Simulate Field Behavior

The university research teams will investigate existing and novel laboratory methods to determine protocols that simulate the two critical aging states needed to design an asphalt mixture to resist rutting and cracking, and provide information on how curing effects the physical and engineering performance of binders and mixtures.The Performing Agencies will provide findings that can be used to cure asphalt mixtures as their rutting and cracking resistance is being evaluated as a part of a mix design process (e.g.,as in the case of a balanced mix design).
