The strength of coarse aggregates is assessed by aggregates crushing test The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load To achieve a high quality of pavement, aggregate possessing low aggregate crushing value ,

The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN 2 APPARATUS 21 An .

The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality 2 Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and
