Los Angeles Abrasion Test
The Los Angeles (LA) Abrasion Test, as described in ASTM C131 and AASHTO T96, is a widely accepted method for determining aggregate hardness and abrasion resistance. This test includes spinning aggregates in a drum filled with steel balls to simulate wear caused by traffic and handling. The degree of wear determines the aggregate's suitability for high-stress applications such as roads, railways, and airport runways. Aggregates with minimal abrasion loss are chosen for surfaces that are frequently impacted and rolled. The LA Abrasion Test guarantees long-lasting construction by finding materials that can withstand mechanical wear for lengthy durations.
Advantages of Los Angeles Abrasion Test:
- Evaluates aggregate wear and durability.
- It simulates mechanical stress from traffic.
- Supports material selection for heavy-duty surfaces.
- Follows ASTM and AASHTO norms.
- Lowers maintenance frequency and expenses.
