ASTM C131
Full Name
ASTM C131 – Standard Test Method for Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine
Scope
ASTM C131 evaluates the resistance of coarse aggregate to wear and tear under a combination of abrasion, impact, and grinding actions.
The scope of ASTM C131 includes:
- Purpose: determining the degradation of small-size coarse aggregate subjected to a specific testing procedure in the Los Angeles abrasion machine.
- Aggregate sizes: coarse aggregates with a maximum size smaller than 37.5 mm (1½ in).
- Test procedure: involves rotating a steel drum containing the aggregate sample and steel spheres. The drum’s rotation causes the aggregate to tumble, leading to wear and tear.
- Evaluation: the degradation of the aggregate is measured by the percentage of material lost after sieving.
Significance:
- Provides a measure of the aggregate’s toughness and durability.
- Helps assess the suitability of the aggregate for use in pavements and other applications subject to abrasion and impact.
ASTM C131 is a valuable tool for material selection and quality control. By simulating the wear and tear experienced by aggregates in real-world conditions, the test helps predict their long-term performance and ensures that they meet specified requirements.
