About This Item
ASTM C131/C131M is the ASTM standard for evaluating the resistance of small-size coarse aggregate to degradation by abrasion and impact in the Los Angeles Machine. It helps users assess how aggregate may perform when exposed to mechanical wear, making it a useful reference for material selection, quality control, and compliance checks. By focusing on a controlled laboratory test, this standard supports more consistent comparison of aggregate durability across projects and suppliers.
ASTM C131/C131M standard overview
The Standard Test Method for Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine provides a defined procedure for measuring how aggregate resists breakdown under combined abrasion and impact. ASTM C131/C131M is commonly used as a technical basis for evaluating small-size coarse aggregate in a repeatable way. The standard is especially relevant when consistency in aggregate performance is important for specification review, acceptance testing, or product qualification.
Where is ASTM C131/C131M used?
This standard is commonly used wherever small-size coarse aggregate is tested for durability before use in construction materials and related applications. It is typically relevant to laboratories, aggregate producers, project specifications, and purchasing or inspection workflows that rely on laboratory test data. ASTM C131/C131M is useful when teams need a recognized method to compare aggregate resistance under the Los Angeles Machine test setup and make informed decisions about material suitability.
Practical importance of ASTM C131/C131M
In practice, ASTM C131/C131M supports more reliable material evaluation by giving buyers, producers, and testing labs a shared method for assessing aggregate degradation. That can help reduce variability in procurement decisions, improve quality control, and support specification compliance. Because the test addresses abrasion and impact resistance, it is often used to help screen materials that may be more likely to break down during handling or service. The result is better confidence in aggregate selection and documentation.
