Fix Your Mix

This article helps readers understand the components of improving asphalt mixes. Specifically, steps can be taken to improve durability, rut resistance, and crack resistance. The author outlines three approaches to improving the asphalt mix: adjust the gradation to ensure adequate voids in the mineral aggregate (VMA), allow for proper air voids in combination with VMA, and understand and control for the impact of reclaimed asphalt pavement (RAP) and reclaimed asphalt shingles (RAS) in the mix. The author also discusses Superpave and the role of state and local regulations and guidelines. Readers are referred to the Asphalt Institute’s “Asphalt Mix Design Methods,” available at, for more information about RAP and RAS.
