[Solved] The aggregate impact value of the aggregate used ...

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

Impact Test on Aggregates

Aggregate impact value (The value of aggregate impact test) = (W1/W2)*100. The value of aggregate impact test should not be more than 45% by weight of aggregates, used for concrete other than wearing surface. An impact value 35% is permissible for the bituminous macadam. Maximum permissible impact value for the water bound macadam is 40%.
