Dec 30 32 Aggregate Impact Value test determines the Aggregate Impact Value AIV of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact Resistance of the aggregates to impact is termed as toughnessAggregate used in road construction should be strong enough to resist crushing under traffic wheel loads If the aggregates are weak the stability of the pavement structure is likely to be adversely affected The strength of coarse aggregates is assessed by aggregate crushing test
