Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage.

One of the tests that are done on aggregate is impact value test. The amount of patients obtained by this way is related to the value of fragmentation and can, in fact, be used as an alternative test. Materials used to test the impact value must pass the sieve No. 1/2 (12.5 mm) and stuck on the sieve No. 3/8 (9.5 mm). The impact test for determining the impact value of materials is used to categorize gravel rocks
