Aggregate Impact Value (AIV) is another index parameter that can be used to measure the hardness of the rocks or crushed stones. Both these LAAV and AIV tests indicate the fracturing resistance of crushed rocks under impact loads. The objective of this research is to find out the relationship between AIV and LAAV of the best rock material,
