Aggregate Impact Value Test as per IS 2386 (Part-IV) 1993. Theory and Scope. The property of a material to resist impact is known as toughness. Due to movement of vehicles on the road, the aggregates are subjected to impact resulting in their breaking down into smaller pieces. The aggregate should therefore have sufficient toughness to resist ...

Impact Test of Aggregate, For constructing any roads, highways, bridges Impact load is important because this type of structure is run-heavy vehicles. so that for concreting work aggregate impact value is very important and every engineer should be known it.. Impact Test of Aggregate. With respect to concrete aggregates, toughness is usually considered the resistance of the material …

aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Two procedures are described, one in which the aggregate is tested in a dry condition, and the other in a soaked condition. The methods are applicable to aggregates passing at 14.0 mm test sieve and

Recommended aggregate impact value Precaution for aggregate impact value test. The sample of aggregate should be sieved in circular motion or movement. The sample aggregate should not be overheated on the oven. The weight of samples and dust should be tamped with the help of a standard size tamping rod.

Concept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate …

Aggregate Impact Value Test. AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load.

Aggregate impact value test gives an indication of aggregate's toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness …

The aggregate impact value test will be conducted as per the Indian Standard Code IS code 2386 Part 4. Let's start with the experiment to understand the concept better. Precautions to be taken. The sample aggregate should be free from moisture.

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 …

Aggregate Impact Tester With Blow Counter: 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 …

The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.

The aggregate impact value indicates a relative measure of the resistance of aggregate to a sudden shock or an impact, which in some aggregates differs from its resistance to a slow compressive load. The method of test covers the procedure for determining the aggregate impact value of coarse aggregates

Test AIV (Aggregate Impact Value, SS 1974) The AIV (Aggregate Impact Value) is a standard test procedure by which the impact strength of aggregates is tested. Just like in Protodyakonov's test, the material used consists of irregularly shaped particles of the -14 + 10 mm size fraction. The weight of the specimen is A.

fresh test made. Two tests shall be made. 5.Calculation 1.The ratio of the weight of fines formed to the total sample weight in each test shall he expressed as a percentage, the result being recorded to the first decimal place: Aggregate Impact Value = (B/A) X 100 where A = weight in g of saturated surface - dry sample,

Determination of Aggregate Impact Value. Theory. Aggregates are the prime constituents of different layers of road pavements. The aggregates are subject to beer the impact load caused by moving vehicles. The property to resist the impact load is termed as toughness. It is determined by aggregate impact value.

Calculate Aggregate Impact Value. The ratio of the weight of fines formed to the total sample weight in each test shall he expressed as a percentage, the result being recorded to the first decimal place: Aggregate Impact Value = W B W A × …

The aggregate impact value indicates a relative measure of the resistance of aggregate to a sudden shock or an impact, which in some aggregates differs from its resistance to a slow compressive load. The method of test covers the procedure for determining the aggregate impact value of coarse aggregates.

Aggregate Impact Value. The test sample shall consist of aggregates the whole of which passes through ½ in B.S. test sieve and is retained on a 3/8 in B.S. test sieve. The aggregate comprising the test sample shall be dried in an oven for a …

In this test we will find out the percentage of the weight of the aggregate sample which gets crushed with respect to the total weight of the sample. This percentage is known as the aggregate impact value and more the aggregate impact value less is the toughness of the road aggregates and vice verse. If impact value is less than 10% then ...

The aggregate impact value test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life. Finding out the impact resistance of aggregate is …

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

The aim and purpose of aggregate impact test is to determine the impact value of the given aggregate which is to be used in road works. Toughness is the property of a material to resist impact. Due to traffic loads the road stones are subjected to the pounding action or impact and there is possibility…
