Impact test Determination of aggregate Impact

2021-3-30  Aggregates are often subjected to impact due to the movement of vehicles on road. Hence it should possess good impact resistance or else it results in disintegration and breaking into pieces. The aggregate impact value gives the relative measure of aggregate resistance to sudden shocks or loads.
