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