Standards. BS 812112. The Aggregate Impact Value Testing Apparatus, meets with BS 812, it is robustly designed to determine the Aggregate Impact Value AIV of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact.
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.
The apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine conforming to IS 2386 Part IV- 1963,IS Sieves of sizes 12.5mm, 10mm and 2.36mm, A cylindrical metal measure of 75mm dia. and 50mm depth, A tamping rod of 10mm circular cross section and 230mm length, rounded at one end and Oven.
The aggregate impact value is defined as a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates may differ from its resistance to a slow compressive load.
Feb 13, 2020 Aggregates used in the construction of roads should be strong enough to resist crushing under traffic wheel loads. It gives relative measure of the resistance of an aggregate to sudden shock or impact. Increase in impact value will indicate reduction in strength of material.
