In cases where the aggregate crushing value is 30 or higher, the result may be anomalous, and therefore, the ten percent fines value should be determined instead. The purpose of conducting this test is to determine the aggregate crushing value of coarse aggregates and evaluate their suitability for use in various types of roads. …

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.
