Aggregate Crushing Value  sarat
Apr 10, 2012 · Calculations: Aggregate Crushing Value = (B/A) * 100 % * The value is higher when more percentage of aggregates crush and break into smaller pieces which indies the aggregates are of a lower quality. * Aggregate crushing value < 45% for aggregates used for concrete for non wearing surfaces and <25% for wearing surfaces like runways and roadways.
