The primary goal of this proposal is to evaluate the viability of asphalt binder in RAP materials using a simplified procedure with the gyratory compactor. The researchers will generate a proposed parameter and recommended thresholds that would allow asphalt mixture suppliers to determine maximum RAP contents based on existing asphalt binder grades, softer binder grades, and recycling agents.

The intended outcome of the project is to provide a quick and accurate means of evaluating recycled asphalt pavement (RAP) that can be utilized back into new asphalt materials.
