crushed faces of aggregate base course material

Pavement layers composed of crushed aggregate particles provide higher strength than pavement layers composed of uncrushed particles. Base course materials are typically required to be crushed because of the strength required near the pavement surface. Some base course specifications require fractured faces on one side (reference is. Get Price

Coarse Aggregate Angularity Pavement Interactive

The CAA test estimates coarse aggregate angularity by visually inspecting a small sample of coarse aggregate and separating the sample into those pieces with a fractured face and those without (Figure 2). If more than one fractured face is specified, the same test can be done using two fractured faces as the decision criteria.
