Abstract: Some results of the stress effects on soil-water characteristics of expansive soils are presented . Based on the experimental results, the first cycle of drying and wetting hysteresis is more significant than others.The stress effects on soil-water characteristic curve of expansive soils are found to be significant. The curve of 1D (one-dimensional stress) and ISO(isotropic stress) looks more linear compared with that from routine test. Hysteresis becomes reversed for the samples under stress.

Key words: unsaturated soils, expansive soil, soil-water characteristic curve, stress controllable volumetric pressure plate extractor
