It is the ability of aggregates that resist sudden impact or shock load on it. Also, it can be defined as the resistance of aggregate to failure by impact load is known as the Impact Value of Aggregate. The characteristic of any material to resist sudden impact is known as toughness. When we use aggregate in roads and …
