To measure this characteristic, the impact value test is conducted. The test determines the aggregate's resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load.
The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. The level and plane concrete floor of a minimum of 45 cm thickness are used to support it.
The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.
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.
Why do we use aggregate impact value test? The aggregate impact value test is done to test the compressive strength of aggregate when sudden and immediate impact force acted on it. It is expressed in percentage (%). It should be less for high impact bearing aggregate for pavement.
The Aggregate Impact Value (AIV) test is a procedure conducted to determine the resistance of an aggregate to sudden impact or shock. This test is crucial in determining the quality and durability of aggregates for use in construction.
The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slow compressive load.

This video demonstrates a aggregate impact value test to determine the aggregate impact value of coarse aggregate. The aggregate impact value gives a relativ...
This Characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load.
In this comprehensive blog post, we will explore the Aggregate Impact Value (AIV) test, a crucial assessment tool that allows construction professionals like you to determine the suitability of aggregates for road construction.
