This document describes a test method for determining the aggregate impact value (AIV) of aggregates, which provides a measure of their resistance to sudden shock or impact. The test involves compacting aggregate samples in a steel cup and subjecting them to 15 blows from a hammer. The crushed material is then sieved and the percentage passing a 2.36mm sieve is . AGGREGATE IMPACT VALUE AIM :- To determine the aggregate impact value of coarse aggregates as per IS: 2386 (Part IV) - 1963. APPARATUS :- 1) Impact testing machine conforming to IS: 2386 (Part IV)- 1963 2) IS Sieves of sizes - 12.5mm, 10mm and 2.36mm 3) A cylindrical metal measure of 75mm dia. and 50mm depth 4) A tamping rod of 10mm circular .The apparatus shall consist of the following: Impact testing machine of the general form shown in Fig.; Sieves-The IS Sieves of sizes 12.5, 10 and 2.36 mm.; Measure - A cylindrical metal measure, tared to the nearest gram, of sufficient rigidity to retain its form under rough usage, and of the following internal dimensions : Diameter 75 mm Diameter 50 mmThe apparatus of the aggregate impact value test as per IS: 2386 (Part IV) – 1963 consists of: 7) A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. It is supported on level and plane concrete
5.1 Impact Value, as determined using the standard 4.5 kg (10 lbm) hammer, has direct application to design and construction of pavements and a general application to earthworks compaction control and evaluation of strength characteristics of a wide range of materials, such as soils, soil aggregates and stabilized soil. Impact Value is one of the properties used to .
Usually in large construction works, whether the available aggregate is suitable or not for the work is determined by the impact value test of aggregate.
