  • Aggregate Impact Value Test - Procedure & Uses

    What is the aggregate impact value test? A relative measure of the resistance of aggregate due to the sudden shock or impact on it is called aggregate impact value. Based on the impact value, we can decide whether the coarse aggregate is suitable for construction or not. This test is performed to ensure the aggregate toughness, which is used in road construction to work as a base layer, sub-base layer.
