The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions See Fig 1 This British Standard a part of the BS 812 series describes a method for the determination of the aggregate crushing value ACV which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load
