test shall be expressed as percentage of the oven dried, the result being recorded to the first decimal place: C Aggregate impact value = A X ]00 where C 11IOII weight of the fines formed, and A = weight of the oven-driedsample. 6. REPORTING OF RESULTS 6.1 The mean of the two results shall be reported as aggregate impact value (wet)ofthe tested .

Aggregate impact value is the measure of the resistance of an aggregate to sudden shock or impact. This test is conducted to determine the toughness of aggregates. This test helps to evaluate the quality of aggregates which can be used in road construction. The specifications for this test are given in IS : 2386 Part IV 1963 mechanical properties. Aggregate Impact Value Test | Transportation Engineering Laboratory | In this video,Demonstration of Aggregate Impact Value Test on aggregate is demonstrated. Objective. To estimate the aggregate impact value of given sample. IS Standards used:IS: 2386(Part-4)-1963 Need and scope:The ‘Aggregate Impact Value’ gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slow compressive load.The property of a material to .

The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine. The material is filled in 3 layers where each layer is .Procedure of 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. (i) Sieve the material through 12.5 mm and 10.0mm IS sieves.
