Aug 29, 2015· 1. OBJECTIVE To assess the resistance of an aggregate to mechanical degradation by the Aggregate Impact Value. BACKGROUND When a road aggregate has been manufactured to a specified grading it is stockpiled, loaded into trucks, transported, tipped, spread and compacted.

Feb 04, 2011· 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 should be preferred

aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS The apparatus of the aggregate crushing value test .
