Characteristic significance test designation* requirement or item reported resistance to abrasion index of aggregate quality; astm c 131 (aashto t 96) maximum percentage of and degradation wear resistance of floors and astm c 535 weight loss. 3.2 abrasion resistance and aggregate crushing value coarse aggregate before being used normally subjected wearing due to many process including transporting and stockpiling.

C131/c131m test method for resistance to degradation of small-size coarse aggregate by abrasion and impact in the los angeles machine c136/c136m test method for sieve analysis of fine and coarse aggregates abrasion value (l.a.a.v) standards: los angeles abrasion test is suitable for coarse aggregate of different sizes and it is not used for fine aggregate. los angeles abrasion value (l.a.a.v.): is obtained from this test and it measures the wear of the material due to abrasion and attrition. l.a.a.v. = original mass - retained mass (at sieve # 12) \ original mass x 100% this value differs

Los angeles abrasion test on aggregate 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) вђ“ this test sorts out aggregates which might be strong but are not resistant to the abrasive action of vehicle tyres if used in the surface course of roads, i.e., though suitable in every other respect, they wear-out too quickly in use.

The aggregate that is retained on the sieve is weighed and the difference between the weight is reported as percentage and given as los angeles abrasion value. procedure the sample obtained is cleaned and dried in oven at 105 to 110 degree celsius. value the aggregate impact test is considered to be an important test to assess the are higher (on the average, by about 5) than the aggregate crushing values. aggregate - afrisam specific application where concrete density is an important factor, eg concrete used

Abrasion test aim of the experiment: to determine the abrasion value of given aggregate sample by conducting losangeles abrasion test. determination of aggregate abrasion value the test gives a measure of the resistance of aggregate to surface wear by abrasion. the dorry abrasion test was superseded in 1951 by the current aav test.

Determination of Aggregate Impact Value – Impact Test on. Determination of aggregate impact value ␓ impact test on aggregates is done to carry out to: determine the impact value of the road aggregates, assess their suitability in road construction on the basis of impact value. The aggregate retained on the sieve is weighed and the difference between this weight and the original weight is expressed as a percentage and reported as the l.a. abrasion loss value. introduction tests for resistance to abrasion in crushed rock, slag, crushed and uncrushed gravel can using los angeles testing method..
