AGGREGATE IMPACT VALUE TEST
The Aggregate impact value indicates a relative measure of resistance of aggregate to impact load which has different effect than the resistance to gradually increasing compressive stress. A test designed to evaluate the toughness of stones or the resistance of the aggregates to fracture under repeated impacts is called impact test.

Aggregate Crushing Value Test
Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary.
