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 are applicable to aggregates passing at 14.0 mm test sieve and retained on a 10.0 mm test sieve. For smaller size fractions, a recommended method is described in appendix A.
Aggregate sizes larger than 14 mm are not appropriate to the aggregate impact value test.
NOTE 1 For the determination of the resistance of an aggregate to a slowly applied compressive load, see BS 812-110.
NOTE 2 The titles of the publications referred to in this standard are listed in the inside back cover.
