The Crushing Value test measures the ability of an aggregate to resist crushing under a compressive load. It is a measure of the strength and toughness of the aggregate. In this test, a standard crushing load is applied to a prepared aggregate sample, and the percentage of fines generated after the specified amount of crushing is determined.
