aggregate crushing value test in

Jan 25 32 The aggregate crushing value is an indirect measure of crushing strength of the aggregat Low aggregate crushing value indicates strong aggregates as the crushed fraction is low Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement componentsThe aggregate crushing value ACV provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Two versions available 150 standard and 75 mm dia The apparatus comprehend cylinder plunger base plate tamping rod and measure
