SPR-4909: Evaluation of Superpave 5 Asphalt Mixtures with Volume of Effective Binder Specification Changes

After a thorough laboratory investigation and several trial field projects, Indiana Department of Transportation (INDOT) adopted the necessary specification changes to make the Superpave 5 asphalt mixture design method the standard asphalt mixture design method in Indiana. Today, the first Superpave 5-designed asphalt mixtures have reached 5 years of service life and therefore the data exists to further evaluate the hypothesis that increased as-constructed asphalt pavement density increases asphalt pavement performance. This project will collect and analyze the data to compare Superpave 5 and the previously standard Superpave 4-designed asphalt mixtures.
