Stone Skeleton Asphalt: Concept Evaluation
A study to evaluate a stone matrix asphalt (SMA)- like asphalt mixture termed “stone skeleton asphalt” was conducted. The concept of stone skeleton asphalt was a mixture that would have similar performance characteristics to typical SMA mixtures, but without the elements contained in SMA mixtures that increase its cost. These elements include: modified asphalt binders, fibers, and mineral fillers. A 19.0 mm nominal maximum aggregate size (NMAS) limestone/granite blend SMA was used as a control mixture, from which cost increasing elements were systemically removed to assess their influence on volumetrics, draindown, and performance. Performance tests included resistance to rutting and falling-head permeability testing.
