ASTM D75
Full Name
ASTM D75 – Standard Practice for Sampling Aggregates
Scope
ASTM D75 provides comprehensive guidelines for sampling aggregates, a critical component in various construction materials. This standard ensures that collected samples accurately represent the properties of the aggregate material, enabling reliable testing and quality control.
Key considerations in ASTM D75 include:
- Sample size: the appropriate sample size is determined by the intended use of the aggregate and the specific properties being tested. Larger samples are generally required for more critical applications.
- Sampling location: representative sampling points are selected from the aggregate stockpile or delivery vehicle. Care is taken to avoid areas where segregation or contamination may occur.
- Sampling methods: ASTM D75 outlines various sampling techniques, such as increment sampling and grab sampling. These methods are chosen based on the type of aggregate, the size of the stockpile, and other relevant factors.
- Sample handling: proper storage and transportation of samples are essential to prevent contamination and degradation. Samples should be protected from moisture, extreme temperatures, and exposure to foreign materials.
Applications of ASTM D75:
- Quality assurance: ensuring that aggregates meet specified requirements for construction projects, such as compressive strength, abrasion resistance, and freeze-thaw durability.
- Research and development: evaluating the performance of different aggregate types and sources in various applications, including concrete, asphalt, and mortar.
