Here, the soil is allowed to swell under a series of different vertical pressures (typically including the estimated overburden pressure). The engineer records the percent swell at each load. This method helps predict how much a foundation will heave under a specific structural load. Astm D4546-21 Pdf

ASTM D4546-21 defines laboratory testing procedures to evaluate the one-dimensional swell or collapse potential of unsaturated cohesive soils under specific loading conditions. The standard outlines three methods—A, B, and C—used by engineers to predict soil behavior when wetted, aiding in foundation design for expansive or collapsible sites.

If you are still using the 2014 or older versions, it’s time to update your manual. While the core physics remain the same, the 2021 update includes: St ASTM D4546-21 in English | PDF Download

This standard (Active Standard D4546-21) covers three alternative methods for determining the magnitude of one-dimensional swell or collapse of compacted or intact soils when subjected to changes in wetting and stress conditions. It is essential for geotechnical engineering applications involving foundations, embankments, and road subgrades.
