Laboratory Rock & Soil Testing
Measurements of drying and wetting permeability

ABSTRACT: Direct measurement of a permeability function, k( ) (where  is suction), of an unsaturated soil is often tedious and time-consuming. Thus, researchers have proposed various semi-empirical predictive methods to determine k(...

The Axis-translation and Osmotic Techniques in Shear Testing of Unsaturated Soils

Abstract: Matric suction in the laboratory testing of an unsaturated specimen is usually controlled by the axis-translation technique or the osmotic technique. To investigate possible differences in the axis-translation and osmotic techniqu...
