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. The general test procedure of the aggregate impact value test is briefly described below: Objectives of Impact Test. 1. To assess the suitability of the aggregate to be used in the highway pavement. 2. To determine the aggregate impact value. Apparatus Required. 1. An impact testing machine weighing between 45kgs to 60 kgs with a metal base.The impact value of aggregate measures how well a material can resist sudden, strong resistance, as aggregates with higher impact values are taken into consideration as much less durable and more liable to cracking beneath sudden masses, which may additionally affect the first-class of production. and Also, may affect sturdiness.
