(PDF) DETERMINATION OF AGGREGATE IMPACT VALUE

DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS 812-112) Scope: 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. Principle A test specimen is compacted, in a standardized manner, into an open steel cup.
