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
23/01/2018· Aggregate impact value = B/A x 100% iii) Two such tests should be carried out and the mean of the results should be reported. A sample proforma for the record of the test results is given in the below table. APPLICATION S OF AGGREGATE IMPACT VALUE.

17/11/2017· The value of aggregate impact test should not be more than 45% by weight of aggregates, used for concrete other than wearing surface. An impact value 35% is permissible for the bituminous macadam. Maximum permissible impact value for the water bound macadam is 40%. The price of aggregate impact testing machine is approximately Rs 4000 to 6000 in India.

Basically the AIV is,Aggregate Impact Value Calculator, Test on course and,Why to test Aggregate Impact Value? Toughness is the property of a material to resist impact. 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,
Aggregate impact value test Machine Take a sample of aggregate and sieve with the help of a 12.5-millimeter sieve and retain it into a 10-millimeter sieve. Sieving should be done in a circular motion. After that sample should be sieved with 10 millimeters sieve and collect in a container. Now, the collected sample of aggregate is heated in an oven at 110 degree Celsius till 4 hours. Now, take,Aggregate Impact Value - Civil Engineering,AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse aggregates as per IS: 2386 (Part IV) – 1963.
