Dec 15, 2017· The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load. From the calculations done we know that the aggregate can be acceptable as their Aggregate Impact value is less then 20% Aggregate Impact Value 10.
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

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%.
