AGGREGATE ABRASION VALUE This test helps to determine the abrasion value of coarse aggregates as per IS: 2386 (Part IV) – 1963. The apparatus used in this test are Los Angles abrasion testing machine, IS Sieve of size – 1.7mm, Abrasive charge – 12 nos. cast iron or steel spheres approximately 48mm dia. and each weighing between 390 and 445g ensuring that the total weight of
30/05/2020 The word abrasion is termed as the process of scraping or wearing something away. This Abrasion effect occurs on aggregates when heavy vehicles move over the granular base. According to IS 2386 (Part IV of 1963), there are two methods for finding out the abrasion value of coarse aggregates namely. By using Devil abrasion testing machine
17/06/2020 Los Angeles's abrasion test on aggregates is a measure of aggregate toughness and abrasion resistance such as crushing, corrosion and disintegration. Aggregate abrasion characteristics are important because the component aggregates in HMA (Hot Mix Asphalt) must resist crushing, degradation, and disintegration to produce high quality HMA.

The resistance offered by aggregate to abrasion is determined in the laboratory by the Los Angeles test machine. The Working principle of the Los Angeles abrasion test is to produce abrasive action by use of standard steel balls, which when mixed with aggregates and rotated in a drum for some specified time for a specific number of revolutions also causes an impact on aggregates.
The Abrasion Machine is used to determine the Aggregate Abrasion Value (AAV) by testing the measure of the resistance of aggregates to surface wear by abrasion. The Abrasion Machine consists of a flat circular cast iron grinding lap wheel of 600 mm dia. which rotates in a horizontal plane at a speed of 28-31 r.p.m. The abrasion sand is fed across the surface of the specimen sample through a ...
Los Angeles Abrasion Value. The Determination of resistance to Fragmentation. This test is carried out in accordance with BS EN 1097-2 and has two methods the most commonly used and well known Los Angeles test and the impact test method. The test is used to determine the wear of aggregates used in building and civil engineering sector. The test simply determines the resistance of the aggregate ...

Abrasion and skid resistance of an aggregate are essential when the aggregate is to be used in concrete constantly subject to abrasion as in heavy-duty floors or pavements. Different minerals in the aggregate wear and polish at different rates. Harder aggregate can be selected in highly abrasive conditions to minimize wear.
