(PDF) DETERMINATION OF AGGREGATE IMPACT VALUE

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 aDetermination of Aggregate Impact Value - Impact Test on,,22/02/2010· The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.Aggregate Impact value Test Apparatus, Procedure and,01/07/2019· Theory and Concept on aggregate Impact value In physical meaning toughness is property of a material to resist impact. Due to movement of vehicle on the road the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregates should therefore have sufficient toughness to resist their disintegration on due to impact. This characteristics is

Due to traffic loads the road stone are subjected to the pounding action of impact and there is possibility of breaking into smaller pieces. The road stone should therefore be tough enough to resists fracture under impact. A test designed to evaluate the toughness of stones i.e. the resistance of the,
