To appreciate the value of your PDF, you must know where D4546-21 fits in the geotechnical testing landscape.
ASTM D4546-21 establishes laboratory test methods (A, B, and C) to determine the one-dimensional swell or collapse of soils, crucial for assessing foundation stability. This updated standard focuses on measuring free swell, swell pressure, and hydrocompression to predict soil behavior under moisture changes.

ASTM D4546-21 establishes procedures for measuring one-dimensional swelling or collapse in unsaturated soils, essential for geotechnical assessments of ground movement. The standard covers three methods (A, B, and C) to simulate compacted fills or analyze intact samples under specific vertical loads. For the full technical document, visit ASTM International.
