Aggregate Impact Value. AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse . and 230mm length, rounded at one end and Oven.Experiment No. 4: Determination of the aggregate impact value of different coarse aggregate samples. (BS 812) Scope & significance: Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
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.Impact value of an aggregate is the percentage loss pf weight of particles passing 2 sieve by the application on load by mean of 15 blows of standard hammer and drop under specified test condition. The aggregate impact value gives a relation measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs .Aggregate impact value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. It is the percentage loss of weight of particles passing 2 sieve by the application on load by mean of 15 blows of standard hammer and drop under specified test condition.
In the Aggregate impact value test, a small portion of coarse aggregates having a size range between 10 to 12.5 mm, is confined in a 75 mm diameter cylindrical metal measure and subjected to 15 blows by a standard hammer weighing 13.5 to 14.0 kg falling freely from a height of 380±5.0 mm attached to the Impact testing machine (Bureau of Indian .CONCLUSION. From the experiment, the value is 29%, 29%, and 29% are close to the maximum allowable limit for good aggregates. Hence, they can be acceptable as their Aggregate Impact value is less than 30%. Aggregate ImpactValues, (AIV's), below 10% are regarded as strong, and AIV's above 35% would normally be regarded as too weak for use in .
A holistic understanding of the material's properties necessitates an amalgamation of findings from multiple tests.

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. Aggregates impact value (AIV) test. The aggregate impact value test was conducted according to the BS 812 standard to determine the resistance to sudden impact or shock. Aggregates ranging in size from 10.0 mm to 12.5 mm were utilized. Initially, the aggregates were dried by heating at 105 °C for a period of 4 hours and then cooled. 3. Impact Value. Impact Test on Aggregates: Understanding the aggregate’s capacity to withstand sudden loads or forces is crucial. The impact test involves subjecting the aggregate to repeated blows and calculating the impact value: [ Aggregate Impact Value = \left(\frac{W_2}{W_1}\right) \times 100\% ] 4.
