The Aggregate Impact Value (AIV) test, outlined in IS 2386 Part IV, evaluates the impact resistance of aggregates. This is performed with an impact testing apparatus, using a specific procedure and sample preparation method. Aggregates acceptable for wearing surfaces in concrete should not exceed a 45% impact value and for bituminous concrete, 30%. The …
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. 2.
Procedure. Step 1 – First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10 mm sieve. Step 2 – Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then, …
Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the …

Aggregate Impact Value (AIV) = B/A x 100. Where B = weight of aggregate passing through 2.36 mm sieve. A = weight of the oven – dried sample. Note. AIV should not be more than 45% for use in concrete other than …
compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. Also aggregate sizes larger than 14 mm are not appropriate to the aggregate impact test. The standard aggregate impact test shall be made on aggregate passing a 14. mm BS test sieve and retained on a 10.0 mm BS test sieve. If required ...
Aggregate Impact Value Used to determine the impact value of aggregates and select them for a given application. The device has a trip-action hammer release, blow counter device and a built-in operator safety device.
The aggregate impact value is expressed as the percentage of the fines formed w.r.t the total weight of the sample. Aggregate Impact Value (AIV) = (100*M2)/M1. Where: M1 …

Aggregate Impact Value (AIV) The apparatus has been designed in a particularly heavy duty form, with specially hardened steel surfaces for minimum wear. The assembly is heavily plated to ensure corrosion resistance and forms a rigid frame around the quick-release trigger mechanism, which ensures an effective free fall of the hammer when released.

Understanding Aggregate Impact Value. Toughness is the property of a material that determines its ability to withstand impact. On roads, aggregates are constantly subjected to impacts from moving vehicles, which can cause them to break down into smaller pieces. It is crucial for aggregates to possess adequate toughness to withstand such impacts ...
