The Aggregate Impact Value Test is important because it helps to determine the quality and suitability of aggregates for use in road construction. Aggregates that have a low AIV value are generally considered to be more suitable for use in road construction, as they are able to withstand the impact and abrasion caused by vehicles.

Determination of Aggregate Impact Value - Impact Test on Aggregates is done to carry out to: Determine the impact value of the road aggregates, Assess their suitability in road construction on the basis of impact value. Aggregate Impact Value on Coarse ...

2023年12月3日 · To measure this characteristic, the impact value test is conducted in an aggregate testing laboratory. The test determines the aggregate's resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load.

What is the aggregate impact value test? A relative measure of the resistance of aggregate due to the sudden shock or impact on it is called aggregate impact value. Based on the impact value, we can decide whether the coarse aggregate is suitable for construction or not.

Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Principle A test specimen is compacted, in a standardized manner, into an open steel cup.

this standard, if the final value, observed or calculated, is to be rounded off, it shall be done in accordance with IS:2-1960t. 1. SCOPE 1.1 This standard covers the procedure for determining the aggregates impact value ofsoft coarse aggregate used for bases and sub-basesof road pavements. 2. APPARATUS 2.0 The apparatus shall consist ofthe ...

2024年1月1日 · The Aggregate Impact Value (AIV) test is a procedure conducted to determine the resistance of an aggregate to sudden impact or shock. This test is crucial in determining the quality and durability of aggregates for use in construction.

Why do we use aggregate impact value test? The aggregate impact value test is done to test the compressive strength of aggregate when sudden and immediate impact force acted on it. It is expressed in percentage (%). It should be less for high impact bearing aggregate for pavement.

2018年1月23日 · Aggregate Impact Value test determines the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Resistance of the aggregates to impact is termed as toughness.
