Testing the compressive strength of the aggregate particles is not normally carried out to determine its strength or suitability. This property is normally determined by a simpler method such as the Aggregate Crushing Value (ACV) or the Los Angeles Abrasion test which also gives a measure of the abrasion resistance and "toughness" of the aggregate.

Why to test Aggregate Impact Value? Toughness is the property of a material to resist impact. Due to traffic loads the road stone are subjected to the pounding action of impact and there is possibility of breaking into smaller pieces. The road stone should therefore be tough enough to resists fracture under impact.
