Superpave5: Potential Asphalt Surface Mix

The Indiana Department of Transportation (INDOT) has adopted Superpave5 as a standard specification on pavement construction projects. Superpave5 is an asphalt mix-design method that targets 5 percent air voids during laboratory design and field placement. Starting in 2013, INDOT demonstrated that layers containing the Superpave5 mixes are constructible without additional equipment or effort. In the short term, these layers exhibit similar environmental impacts as previous Superpave designed mixes and INDOT will continue to monitor to assess long-term performance. This document discusses INDOT's motivation for using the Superpave5 procedure, what was done, what benefits were achieved, and key outcomes/lessons learned.
