Measures the compression or settlement of a soil specimen that is first inundated and then subjected to increasing vertical loads. Key Applications

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
