ASTM D2487

ASTM D2487 is a standardized test used to classify soils based on their physical properties, particularly grain size and soil composition. Engineers and geologists use it to understand soil behavior for construction, foundation design, and earthwork projects. The test involves analyzing soil samples through sieve and hydrometer tests to determine the percentage of sand, silt, and clay. This classification helps predict how soils will perform under load, moisture, and environmental changes, ensuring safe and effective construction practices. In essence, ASTM D2487 provides a consistent way to categorize and understand soil types for engineering purposes.
