Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates.

Coarse aggregate angularity is important to ensure adequate aggregate interlock and prevent excessive HMA deformation under load . Figure 1: Angular Coarse Aggregate. 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).
