Displacements are recorded continuously using digital dial gauges or linear variable differential transformers (LVDTs) until the vertical deformation stabilizes.
: Updated formulas for calculating percent swell and swell pressure to reduce interpretation errors. Astm D4546-21 Pdf
This method involves loading the specimen to various stress increments while dry, inundating it at a specific stress level, and then continuing the loading sequence. This generates a complete stress-strain curve that allows engineers to evaluate soil behavior across a broad spectrum of loading scenarios. Step-by-Step Testing Procedure This generates a complete stress-strain curve that allows
The specimen is inundated with water, and the vertical swell is recorded over time until it stabilizes. : Many university libraries and engineering firms provide
The magnitude of one-dimensional, wetting-induced swell (heave) in unsaturated soils.
: Many university libraries and engineering firms provide access to the ASTM Compass portal for their members.
