Influence of Aggregate Morphology and Grading on the Performance of 9.5-mm Stone Matrix Asphalt Mixtures
The Virginia Department of Transportation has released a report that investigates the stability of stone matrix asphalt (SMA) mixtures grading specifications and the effects of aggregate morphology and asphalt binder properties on their stability. SMA is the typical gap-graded mixture used in Virginia, and is intended to maximize rutting resistance and durability with a stable stone-on-stone skeleton held together by a mixture of asphalt binder.
