The aggregate crushing value test measures which physical property of coarse aggregates used in road construction?
AToughness against impact loading
BResistance to surface abrasion
CStrength against gradually applied compressive load
DDurability against weathering action
Explanation
The Aggregate Crushing Value (ACV) gives a relative measure of resistance of an aggregate to crushing under a gradually applied compressive load (40 tonnes over 10 minutes). Aggregate Impact Value measures toughness, and Los Angeles Abrasion measures wear resistance.
