Impact Value is .A limestone quarry 10 mm graded crushed basalt rock or aggregate, for use in concrete, called "blue metal" in Australia 20 mm graded aggregate A gravel and sand extraction facility in Međimurje County, Croatia Chipseal aggregate on Ellsworth Road in Tomah, Wisconsin. Construction aggregate, or simply aggregate, is a broad category of coarse- to medium .
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 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. .
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's of Science.. As a journal-level metric, it is frequently used as a proxy for the relative importance of a journal within its .
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.
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 Test | Transportation Engineering Laboratory | In this video,Demonstration of Aggregate Impact Value Test on aggregate is demonstrated.[19,20,21,22,23] Kwek and Awang (2018) [19] Water The aggregate impact value test determines the aggregate's resistance to sudden loading [24], which may differ from the resistance to .IS : 2386 (Part IV) ‘- 1963 2.2 Apparatus - The apparatus for the standard test shall consist of following : a) A 15-cm diameter open-ended steel cylinder, with plunger and base-plate, of the general form and dimensions shown in Fig. 1. 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 .
The impact value of aggregate measures how well a material can resist sudden, strong resistance, as aggregates with higher impact values are taken into consideration as much less durable and more liable to cracking beneath .

For testing, the specimen passing through 12.5 mm sieve but retained on 10 mm sieve is filled in 3 layers with 25 time stamping on each layer and then hammer of 13.5 to 14 kg is dropped freely from a height of 38 cm for 15 blows.. Aggregate impact value is then the .
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 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.mass of material to determine the aggregate impact value Grade of the aggregate Minimum mass of test portion All-in aggregate 40 mm max. size All-in aggregate 20 mm max. size Graded aggregate 40 to 5 mm Graded aggregate 20 to 5 mm Graded aggregate 14 to 5 mm 20 kg 15 kg 12 kg 8 kg 5 kg 7.6.5.2 Test specimen in a dry condition
