LA Abrasion Test: Aggregate Abrasion Testing Pt 2

The L.A. Abrasion test uses larger dry samples and abrasive charges in a drum with a shelf. The shelf lifts and drops the sample and abrasive charge across the span of the drum, resulting in a very high impact on the aggregate particles. Loss from this test is a result of fracturing and dry grinding of the particles.
