Jun 08, 2019· The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS2386 Part 4. 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 should be preferred.
Laboratory test equipment for the Aggregate Impact Value (AIV) and the Aggregate Crushing Value (ACV) and Ten Percent Fines Value (TFV) are also available. The Pendulum Skid Resistance Tester provides highway engineers with a method of checking the resistance of wet and dry surfaces to slipping and skidding, both in the lab and insitu.
