    Aug 29, 2019 Aggregate Impact Value Test as per IS 2386 (Part-IV) 1993. Theory and Scope. The property of a material to resist impact is known as toughness. Due to movement of vehicles on the road, the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregate should therefore have sufficient toughness to resist

    Concept: Aggregate Impact Test: It is conducted to determine the toughness of the aggregates. For testing, the specimen passing through 12.5 mm sieve but retained on 10 mm sieve is filled in 3 layers with 25 time stamping on each layer and then hammer of 13.5 to 14 kg is dropped freely from a height of 38 cm for 15 blows. Aggregate impact value is then the percentage of fine passing through 2
