# aggregate crushing value test report discussion

Theory: The “aggregate crushing value” give a relative measure of the resistance of an aggregate to crushing under gradually applied compressive load. It’s the percentage by weight of the crushed(finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the strength of the aggregate used in road construction.
