Los Angeles (L.A.) Abrasion Test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA (Hot Mix Asphalt) samples should resist crushing, degradation and disintegration in order to produce a high-quality HMA.
