The test sample shall consist of aggregates the whole of which passes through ½ in B.S. test sieve and is retained on a 3/8 in B.S. test sieve. The aggregate comprising the test sample shall be dried in an oven for a period of four hours at a temperature of 100-110 °C and .
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 . The impact test involves subjecting the aggregate to repeated blows and calculating the impact value: [ Aggregate Impact Value = \left(\frac{W_2}{W_1}\right) . In conclusion, the selection of appropriate aggregates is a critical factor in the success of pavement construction. Understanding the intricate properties and conducting rigorous . Aggregate Impact Value. AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse . and 230mm length, rounded at one end and Oven.
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 Testing Machine: Consisting of a circular base with vertical publications and a hammer of thirteen.Five to 14 kg mass. . Exceeding this limit indicates that the aggregates are weak and prone to breakage or fragmentation under impact loads. Conclusion.
