Los Angeles Abrasion Testing Machine
Los Angeles abrasion machine for measuring the abrasion resistance (hardness) of coarse aggregate per IS 2386 (Part 4).
NABL TC-14144·
ISO/IEC 17025:2017·
Lab ID NKM/EQ-197
The Los Angeles Abrasion Testing Machine measures the abrasion resistance of coarse aggregate by tumbling it with a charge of steel spheres for a set number of revolutions and weighing the material worn away. The LA Abrasion Value is a core acceptance criterion for road and concrete aggregates, per IS 2386 (Part 4).
What this equipment tests
- Los Angeles Abrasion Value of coarse aggregate
- Hardness / durability assessment for pavement aggregate
- Acceptance against MoRTH / IS 383 limits
Applicable Indian Standards
- IS 2386 (Part 4) — Mechanical properties of aggregates — abrasion value
- IS 383 — Coarse and fine aggregate — specification

Frequently asked questions
What is the Los Angeles abrasion test?
It measures how much an aggregate wears down under abrasion and impact from a steel-ball charge; lower loss means harder, more durable aggregate.
Which standard is used?
IS 2386 (Part 4).
