This testing method is known as an aggregate crushing value test. The crushing value test of aggregate provides the resistance of an aggregate sample to crushing under a gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on a 10 mm sieve.

Aggregate crushing value = (W2 x 100) / (W1-W) W2 =Weight of fraction passing through the ...

Aggregate crushing value is a test for the measurement of an aggregate's resistance to crushing under a gradually applied compressive load. It is used to determine the strength and suitability of the aggregate for different construction purposes.

What is an aggregate crushing value? The resistance capacity of aggregate under gradually ...

Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.

This document gives the determination of aggregate crushing value ( ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the gradually applied compressive load. The method is applicable to aggregates passing a 14,0 mm test sieve and retained on a 10,0 mm test sieve.
