importance of aggregate crushing value test

importance of aggregate crushing value test

Aggregate crushing value test providesstrength of aggregates for resistance against crushing under loads and is used for roads and pavements construction. Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load
