To determine the . 1.2 Aggregate impact value test (AIV) The aggregates are exposed to impact d ue to the passage of . vehicles on the road, resulting in their breaking down into . smaller parts.
The observations in the Impact Test are recorded, including the total weight of the dry sample (W1 gm), weight of portion passing the 2.36 mm sieve (W2 gm), and the calculated Aggregate Impact Value in percent. Significance of Aggregate Impact Value. The Aggregate Impact Value is used to classify aggregates based on their suitability for .aggregate crushing value of coarse aggregate. NOTE 1 -The ‘aggregate crushing value’ gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate of ‘aggregate crushing value’ 30 or higher, the result may be anomalous, and in
AIV Test Lab Report. Also, Read: Laboratory Test on soil – Procedures and Objective Aggregate Impact Value Limits As Per IS code: Aggregates are essential ingredients for making concrete, and the properties of concrete are substantially affected by various characteristics of the aggregates used.Impact value of aggregate satisfactory for road surfacing? . Aggregate Impact Testing Machine: Consisting of a circular base with vertical publications and a hammer of thirteen.Five to 14 kg mass. Cylindrical metallic degree with an inner diameter of 75 mm and a height of fifty mm.The aggregate impact value is the proportion of the sample that passes a 2.36 mm sieve after the hammer impacts. European Standards will not contain the 10 per cent fines test or the aggregate impact value test (although a different impact test, the German Schlagversuch test, has been included). AGGREGATE IMPACT VALUE This test is done to determine the aggregate impact value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine conforming to IS: 2386 (Part IV)- 1963,IS Sieves of sizes – 12.5mm, 10mm and 2.36mm, A.
Aggregate impact value is the measure of the resistance of an aggregate to sudden shock or impact. This test is conducted to determine the toughness of aggregates. This test helps to evaluate the quality of aggregates which can be used in road construction. The specifications for this test are given in IS : 2386 Part IV 1963 mechanical properties. Detailed Impact Test on Road Aggregates with calculation of Impact value has been shown, also range of aggregate impact value is explained.Toughness is the p. The Aggregate impact value indicates a relative measure of resistance of aggregate to impact load which has different effect than the resistance to gradually increasing compressive stress. A test designed to evaluate the toughness of stones or the resistance of the aggregates to fracture under repeated impacts is called impact.
The aggregate impact value test is an important test of aggregates. It is done to obtain the resistance and impact of aggregates (stones). In this test a machine is used, which is called impact testing machine. 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 =Mass of the test specimen M2 = Mass of the test specimen passing 2.36 mm test sieve

The apparatus shall consist of the following: Impact testing machine of the general form shown in Fig.; Sieves-The IS Sieves of sizes 12.5, 10 and 2.36 mm.; Measure - A cylindrical metal measure, tared to the nearest gram, of sufficient rigidity to retain its form under rough usage, and of the following internal dimensions : Diameter 75 mm Diameter 50 mm Aggregate Impact Value Testing machine. The test equipment and the test procedure are quite simple and it determines the resistance to impact of stone aggregates simulating field condition. This test can be performed even at construction site or at stone quary, as the apparatus is simple and portable. .test shall be expressed as percentage of the oven dried, the result being recorded to the first decimal place: C Aggregate impact value = A X ]00 where C 11IOII weight of the fines formed, and A = weight of the oven-driedsample. 6.

The method of aggregate test specifies the procedure for determining the aggregate impact value of coarse aggregate. Aggregate impact value is used to classify the stones in respect of their toughness .
This video demonstrates a aggregate impact value test to determine the aggregate impact value of coarse aggregate. The aggregate impact value gives a relativ.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 .
The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine. . Aggregate impact value = (W1/W2)*100. Aggregates to .Observations and Calculations Calculate the aggregate impact value (AIV) expressed as a percentage to the first decimal place for each test specimen from the following equation: Where (𝐴𝐼𝑉) = 𝑀2 × 100 𝑀1 M 1 is the mass of the test specimen (in g); M 2 is the mass of the material passing the 2.36 mm test sieve (in g .
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%.
This Characteristic is measured by impact value test. 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. Apparatus Required: Impact Testing Machine: Impact testing machine conforming to IS: 2386 (Part IV) - 1963, as shown in Figure 1. .The aggregate impact value gives a relative measure of the resistance of the aggregate to sudden shock or impact. . 7.6.6 Aggregate impact value 7.6.6.1 Procedure a) Test specimens in a dry condition (i) Fix the cup firmly in position on . Aggregate Impact Value Test | Transportation Engineering Laboratory | In this video,Demonstration of Aggregate Impact Value Test on aggregate is demonstrated.
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 . 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. In this article, we will discuss the complete procedure of conducting an AIV test, from the introduction to .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 compressive load. . and allowed to fall freely on to the aggregate.
