Jun 17, 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 abrasion test is conducted on the aggregates to know its toughness and resistance such as crushing, degradation and disintegration. It is more like a Charpy impact test for metal toughness. It is conducted in three different methods.
