This E-Circular was developed from presentations made during the 95th Annual Meeting of the Transportation Research Board in a workshop titled Innovations in Asphalt Mix Design Procedures. The fundamentals of asphalt mix design are examined for improved durability and performance along with recent advancements in specifications and construction. Common themes include strategies that yield more binder into the mix with trials that modify the air void and void in mineral aggregate requirements that complement the Superpave system. Methodologies to incorporate rejuvenators for increased reclaimed asphalt pavement and recycled asphalt shingles are presented. Performance testing ties together these approaches the concepts shown for balanced mix designs. The benefits of achieving adequate field compaction and comparisons of these innovative mix design and performance evaluations from field test sections are explored.
