Methods for determination of aggregate impact value

2019-10-18  This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Two procedures are described, one in which the aggregate is tested in a dry condition, and the other in a soaked condition. The methods
