Why The Aggregate Crushing Value Test Is Done
Rock Aggregates and Its Suitability | Geology
This may be assessed by tests of aggregate impact value (AIV) and aggregate crushing value (ACV). The common rock types range in AIV from good (basic volcanic, dolerite, quartzite. quartz gravels), through fair (granite, gravels composed of igneous or metamorphic fragments) to poor (weathered igneous rocks, clayrich gravels).
