Influence of laboratory aggregate compaction method on

2020-10-30  1. Introduction. Stone Mastic Asphalt (SMA) exhibits good performance, especially when applied in wearing courses, due to its high resistance to rutting , .A key factor contributing to its improved performance is attributed to the aggregate quality , and the structure created by the SMA non–continuous gradation , , which promotes stone–on–stone contact in the large size aggregates.
