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 charge is 5000 +25g and …

Los Angeles Abrasion Test on Aggregates -Values for Pavements

Los Angeles abrasion test on aggregates is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is carried out by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine.

AGGREGATE ABRASION VALUE (AAV) - GEOTECHNICAL

AGGREGATE ABRASION VALUE (AAV) 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 Aggregate Abrasion machine determines the Aggregate Abrasion Value by testing the measure of the resistance of aggregate to surface wear by abrasion.

Los Angeles Abrasion Test Procedure, Method, Significance ...

L.A. abrasion loss seems to be reasonable well correlated with dust formation during handling and HMA production in that aggregates with higher LA. abrasion loss values typically generate more of dust. Uses & Significance of LA Abrasion Test : For an aggregate to perform satisfactory in pavement, it must be sufficiently hard to resist the abrasive effect of traffic over long period of time.

Aggregate impact and - SlideShare

Feb 08, 2012 · The mean of the two test results is reported as the aggregate abrasion value.Discussion The aggregate abrasion test given above is rapid and easy to perform, except for the preparation of testspecimen, which is difficult and time consuming. This test is however carried out commonly in U.K.and a few other countries.

AGGREGATE IMPACT VALUE TEST-10+ IMPORTANT NOTES TO ...

Jul 16, 2014 · Aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates. It has been found that for majority of aggregates, the aggregate crushing value and aggregate impact values are numerically similar within close limits.

Los Angeles Abrasion Test Procedure, Apparatus ...

Principle of the Test: To produce the abrasive action by use of standard steel balls which when mixed with the aggregate and rotated in a drum for specific number of revolution cause impact on aggregate. The %age wear due to rubbing with steel balls is determined and is known as abrasion value.

Aggregate Abrasion Value Test - Learning Technology

Nov 29, 2019 · Abrasion testing of aggregate is one of more direct application to the testing of stone aggregate for wearing. The aggregate which shows a low loss in this test is generally hard, tough, resistant to abrasion and strong. These are also desirable …

Abrasion Test on Aggregate (Los Angeles Test) - Civiconcepts

Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in Los Angeles Machine.

Effects of Los Angeles Abrasion Test Values on the ...

aggregate samples to calculate the LA abrasion loss. The authors found that the LA abrasion test was a consistent method of detecting weak materials and was a means of pre­ dicting aggregate impact value and aggregate crushing value. Wylde (11) reviewed and investigated the road failures,

ASTM C131 / C131M - 14 Standard Test Method for Resistance ...
