The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied compression load. Aggregates possessing high resistance to crushing or low aggregate crushing value are preferred for use in high quality pavements. The apparatus for the standard test consists of a steel cylinder 152 mm diameter with a.The strength of coarse aggregates is assessed by aggregates impact test. The aggregate impact value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, lower aggregate impact value should be preferred. Toughness is the property of a material to resist impact.
