(PDF) DETERMINATION OF AGGREGATE IMPACT VALUE

DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS 812112) 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 cupThis degree is assessed by a sieving test on the impacted specimen and is taken as the aggregate impact value (AIV) 4 Sampling The sample used for the test (the laboratory sample) shall be taken in accordance with clause 5 of BS 812102:1989 5 Apparatus NOTE All apparatus should comply with the general requirements of BS 812100 51 GeneralBS8121121990 Aggregate Impactpdf British Standard
