Impact and Crushing Value - PCTE

UTA-0650. The Aggregate Impact Value Testing Apparatus is robustly designed to determine the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. The number of blows delivered to the sample is automatically documented by the counter that is fitted to the machine.
