Abstract
The soil-water Retention curve (SWRC) has been used as a tool by geotechnical researchers and practitioners to determine the properties such as the shear strength, coefficient of permeability, bearing capacity and the modulus of elasticity of unsaturated soils. Such studies are valuable to the practicing engineers as they alleviate the use of time consuming and elaborate testing techniques required for determining the unsaturated soil properties. In this paper, an attempt is made to study the relationship between the SWRC and the swelling pressure including the one dimensional swell behavior for two different expansive soils using statically compacted specimens. Test results were analyzed to evaluate the clay mineralogy and influence of initial compaction moisture content or matric suction on both swell strain and swell pressure properties in one-dimensional test conditions. Comparisons of swell pressures and swell strain potentials and related SWRC properties of these soils are also made.
