This document describes the procedure for determining the aggregate crushing value (ACV) of aggregate materials. The ACV test involves crushing a sample of aggregate between 9.5mm and 13.2mm under a gradually applied 400kN load. The percentage of material crushed finer than 2.36mm is calculated and reported as the ACV. The test can …
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. 2. apparatus required

The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. Why to test Aggregate Crushing Value? The principal mechanical properties required in road …
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.
