An Aggregate Impact Tester is a device used in civil engineering to evaluate the toughness of aggregates—materials like gravel or crushed stone used in construction—by measuring their ability to resist sudden impact or shock. This test helps determine the suitability of aggregates for use in road construction, pavements, and other infrastructure projects …
1. The aggregate impact test determines a material's resistance to sudden shock or impact. Road stones must withstand pounding from traffic. 2. The test involves compacting aggregates between 10-12.5mm in a metal cylinder, subjecting it to 15 blows from a falling hammer, then sieving to determine the percentage passing a 2.36mm …
Determine the impact value of the road aggregates, Assess their suitability in road construction on the basis of impact value. Aggregate Impact Value on Coarse Aggregates Apparatus for Aggregate Impact Test The apparatus consists of: (i) A testing machine weighing 45 to 60 kg and having a metal base with a painted
The document discusses the aggregate impact value (AIV) test for determining the toughness and resistance to impact of aggregates used in road construction. An AIV test was conducted on three aggregate samples, finding mean values of 22.11%, within the satisfactory range of 20-30%. The AIV test is a simple and quick way to simulate field …
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. ... Bitumen adheres well to all normal types of road ...
The Aggregate Impact Value is used to classify aggregates based on their suitability for different types of road construction. The classification is as follows: <20%: …
Aggregate Impact Value (AIV) test indicates the toughness of aggregates. It is measured as percentage of aggregates passing through 2.36 mm IS sieve to the weight of aggregates taken. Higher the AIV ⇒ more aggregates gets broken during impact ⇒ lower the toughness or weak aggregate. Statement II – True
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.

AGGREGATE IMPACT TEST INTRODUCTION. When a road aggregate has been manufactured to a specified grading it is stockpiled, loaded into trucks, transported, tipped, spread and compacted. If the aggregate is weak, some degradation may take place and result in a change in grading and/or the production of excessive and undesirable fines.
The apparatus is designed with a sturdy frame and a hardened steel base plate to withstand the repetitive impact forces applied during testing.The device includes a hammer, typically weighing 13.5 kg, which is dropped from a set height (usually 380 mm) onto a cylindrical sample of aggregates to simulate impact forces.The Aggregate Impact Value test …
