Place the mould in the aggregate impact testing machine and administer 15 numbers of blows of a metal hammer. After that, remove the crushed aggregate and sieve it through a 2.36 mm sieve. The aggregate impact value is measured as % of aggregates passing through the 2.36mm sieve (W2) to the total weight of the sample (W1).

Therefore, the aggregates should have sufficient toughness to resist their disintegration due to the impact. This distinctive property is measured by impact value test. The aggregate impact test value is a measure of resistance to sudden impact or shock, which may vary from its resistance to gradually applied compressive load.
