Coarse aggregate, material contained on the No. 4 sieve, shall consist of material of which 25 percent by weight shall be crushed particles. Class 2 aggregate base shall conform to one of the following gradings, determined in accordance with ASTM C136:

The time (10 minutes) is started in the stopwatch. The crushed material is then transferred into the sieve of size 2.36 mm. Sieving is done now and the sample passing through the sieve is collected and weighed. The weight is recorded as W2. Aggregate Crushing Value (ACV) can be determined by using a simple formula: This test is repeated once or ...
