The Characteristics of any material to resist sudden impact is known as toughness. When we use aggregate in roads and pavement on which vehicular movement is done and there is a possibility of impact load on aggregate. This impact load can break aggregate in smaller pieces and which results in the failure of roads and pavements.

Therefore, aggregate used for such propose should have sufficient toughness to resist their disintegration due to the impact. This important property of aggregate is determined by the impact value test.

The need for impact value test is to find out the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.

7 Lab Tests On Aggregate To Check Quality For Use

7 Lab Tests On Aggregate To Check Quality For Use

Find out the impact resistance of aggregate is important because, during service life, the aggregates will be actually subjected to this type of load. For example, aggregates will be subjected to impact after speed breaker, or when the vehicle is moving on the undulating road, etc.

Mar 21, 2018nbsp018332 Aggregate Impact Values, AIVs, below 10 are regarded as strong, and AIVs above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties. Recommended Aggregate Impact Test Values.
