2.0 THEORY 2 Basically the Aggregate Impact Value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling from a set height, a prescribed number of times, onto of aggregate of a standard size and weight retained in a mould.
