Los Angeles Abrasion Test on Aggregates

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.

Abrasion Test

Uses Of The Abrasion Test. For an aggregate to perform satisfactorily on the pavement, it must be difficult enough to resist the abrasive effect of traffic for a long period of time. Soft aggregates will be quickly crushed into powder, while hard aggregates are quite resistant to crushing. The test will also determine the quality of the aggregate.
