The test procedure outlined in ASTM D4546-21 involves the following steps:
: This method involves using a double-ring infiltrometer to assess the rate at which water moves into the soil. It's particularly useful for understanding infiltration rates at the soil surface. astm d454621 pdf
ASTM D4546-21 establishes laboratory methods to measure the one-dimensional swell or collapse potential of unsaturated soils when wetted. The standard outlines three test methods (A, B, and C) to determine key parameters like swell pressure, free swell, and hydrocompression for engineering applications.
