Therefore, the aim of this study is to analyze the impact of the crushing of natural aggregate on the LA crumbling strength index. Two types of aggregates were analyzed—natural gravel and natural pebbles crushed in a crusher. .

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).

It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits. For deciding the suitability of soft aggregates in base course construction, aggregate impact test is commonly used. A modified impact test is also often carried out in the case of soft . 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 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 .This document describes a test to determine the aggregate impact value (AIV) of aggregates used in road construction. The test involves sieving aggregates to obtain samples between 14-10mm in size, drying the samples, compacting them in layers in a steel cylinder, and subjecting the cylinder to 15 blows from a hammer. The aggregates passing through a 2.36mm sieve are .

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 period of four hours at a temperature of 100-110 °C and .

Designation (Number): B.S. 812: Part 112: 1990. Scope: -Testing coarse aggregates for resistance to Impact Aggregates: -combination of sand, gravel, crushed stone, or other material of mineral composition-Natural aggregates taken from quarries (natural deposits)-Manufactured aggregates include blast furnace slag, clay and slate etc. Aggregate .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.

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 test involves placing a sample of the aggregate along with steel balls in the presence of water. The entire assembly is then rotated in a drum for a specified number of revolutions. Fig 2: Deval Abrasion test. During this process, the aggregates undergo substantial wear and abrasion, leading to the generation of fine particles and dust. The Aggregate Impact Value (AIV) test is a common procedure used to assess the resistance of aggregates to sudden impact or shock, reflecting their durability and toughness in construction .

applied compressive load. With aggregate of aggregate impact value (AIV) higher than 30 the result may be anomalous. In addition, aggregate sizes larger than 15 mm are not appropriate to the aggregate impact test.
