To decrease the frictional stresses between the soil and the confining ring of the oedometer apparatus, several techniques were used. A description of the test apparatus and the different techniques to reduce frictional effects are discussed. The merit and the theoretical background of each technique are evaluated. On the basis of experimental results of 28 soil specimens, a semiempirical equation is deduced to determine the value of swelling pressure in terms of initial dry density, initial water content, and clay content of the soil. This equation is compared with other methods of predicting swelling pressures. The semiempirical equation proposed in this paper can be used as a design guide to predict swelling pressures for the expansive soil studied.
