The aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test (although a different impact test, the German Schlagversuch test, has been included).Aggregates used in road construction should be strong enough to resist crushing under traffic wheel loads. The strength of the aggregates may be measured in crushing or impact tests. The Aggregate Impact Value (AIV) gives a relative measure of the resistance of an aggregate to sudden shock or impact.
