  • Los Angeles Abrasion

    The L.A. abrasion test measures the degradation of a coarse aggregate sample that is placed in a rotating drum with steel spheres (Figure 7). As the drum rotates the aggregate degrades by abrasion and impact with other aggregate particles and the steel spheres (called the "charge").
