The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load. The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.

The aggregate crushing value of the coarse RCA and normal coarse aggregate were 40 and 120 MPa, respectively. The water absorption of the coarse and fine RCA, as well as the normal coarse and fine aggregates were measured as being approximately 6.87%, 14.05%, 0.60% and 4.16%, respectively.

APPLICATIONS OF AGGREGATE CRUSHING TEST: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low. Thus the test cans be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.
