Innovations in Asphalt Mixture Design Procedures

Transportation Research E-Circular 237: Innovations in Asphalt Mixture Design Procedures explores the fundamentals of asphalt mix design for improved durability and performance. Based off of presentations made at TRB's 95th Annual Meeting, the document examines presentations that cover ways to incorporate more binder into the mix with trials that modify the air void and void in mineral aggregate (VMA) requirements that complement the Superpave system. Performance testing ties together these approaches the concepts shown for balanced mix designs. The report also explores the benefits of achieving adequate field compaction and comparisons of these innovative mix design and performance evaluations from field test sections.
