2015-10-12 Aggregate crushing value (ACV) and aggregate impact value (AIV) are two well-known British tests for assessing the degradation of aggregate. ACV gives a relative measure of the resistance of aggregate to crushing under a gradually applied compressive load. AIV gives a relative measure of the resistance of aggregate to sudden shock or impact.
