Performance Evaluation of SP-9.5 and SP-12.5 Superpave Mixtures

This project will compare the performance of SP-9.5/FC-9.5 to SP-12.5/FC-12.5 Superpave asphalt mixtures. The research objective is to determine if SP-9.5/FC-9.5 mixtures are at least equivalent to SP-12.5/FC-12.5 mixtures in terms of cracking and rutting resistance. The outcome of this research is needed to determine the best use of aggregate resources.
