    The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under Aggregate Crushing test (IS 2386 (Part 4):1963 BS 812–110:1990) Aggregate crushing test values indicates the strength of aggregate and hence it is very significant Similarly we can say crushing value is the relative measure of resistance of an aggregate under gradually applied compressive loadsfigure of aggregate crushing value test
