Why is Aggregate Crushing Value Test (ACV) Done
Aggregate Crushing Value Test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied load. Aggregates used in construction should be strong enough to resist crushing under high loads e.g., traffic wheel loads. ACV test is commonly conducted on road projects, but can also be used in other sections

The results of the aggregate crushing value test can be classified as follows: 1. Over 35% – Weak aggregates. 2. 35% to 70% – Average quality aggregates. 3. 70% to 90% – Strong aggregates. 4. Above 90% – Exceptionally strong aggregates. In general, the lower the crushing value, the stronger the aggregate will be.

Determination the Crushing Value of Aggregate test
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.
