Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

For example, a graded aggregate of nominal size 12.5 mm means an aggregate most of which passes the 12.5 mm IS Sieve. Because the aggregates are formed due to natural disintegration of rocks or by the artificial crushing of rock or gravel, they derive their many of the properties from the parent rocks.
