Determination of Aggregate Impact Value  Impact Test on ...
Feb 22, 2010 Theory of Aggregate Impact Test 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 aggregates should therefore have sufficient toughness to resist their disintegration due to impact.
