QUALITY ASSURANCE for AGGREGATES

2019-10-1720 mm 10 mm 4.8 mm Fine Flaky aggregate are the aggregates whose least dimension is less than 3/5th of its mean dimension i.e. the mean dimension of an aggregate passing through 40 mm sieve and retained on 20 mm sieve is 40+20/2 = 30 mm. Now if the least dimension is less than18 mm (3/5 x 30 = 18 mm) then the aggregate is flaky.

Coarse Aggregate Angularity

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
