E1-2 3.1—Grading 3.1.1—Definition and test method . aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately.Strength tests, such as the aggregate crushing value (ACV) and aggregate impact value (AIV), assess the aggregate’s ability to withstand stresses. Typical ACV limits are 30% for concrete wearing surfaces and 45% for other concrete applications, while AIV limits range from 20% to 30% depending on the desired concrete strength. The aggregate impact value is a determining measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Aim: – To determine Aggregate Impact Value Using Impact Testing Machine. Apparatus: – Impact Testing Machine: – Weight of hammer is 13.5 to 14.0 kg and Height of Fall is .
The aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test (although a different impact test, the German Schlagversuch test, has been included).🕑 Reading time: 1 minuteDetermination of Aggregate Impact Value - Impact Test on Aggregates is done to carry out to: Determine the impact value of the road aggregates, Assess their suitability in road construction on the basis of impact value.
