    Aggregate Impact Value. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling a set height, a prescribed number of times, onto an amount of aggregate of standard size and weight retained in a mould. Aggregate Impact Values, (AIV’s), below 10 are regarded as strong, and AIV’s above 35 would normally be
