Aggregate Crushing value is a relative resistance of aggregates to crushing under gradually applied compressive load. Aggregate Crushing Value Test is important to test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height.

This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%.
