Los Angeles Abrasion - Pavement Interactive

Overview. The 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 must resist crushing, degradation and disintegration in order to produce a high quality HMA.. Figure 1: L.A. abrasion testing equipment.
