About this test
Calculate the Los Angeles abrasion loss from the mass before the test and the mass retained on the 1.70 mm sieve after 500 revolutions.
How it's calculated
- Loss (%) = (original mass − mass retained on 1.70 mm) ÷ original mass × 100
- ≤ 50% general concrete (ASTM C33); ≤ 40% base & wearing courses
