Expansive soil is one of the problematic soils that have volumetric variability as a result of the change in the moisture content. Expansive soils are widely present in semi-arid and arid regions of the world. The swelling behavior of these soils can be characterized by swelling parameters; swelling pressure and swelling potential. The swelling pressure of expansive soils, has major influence on foundations of buildings and infrastructures such as houses, highways, pipelines and other structures. It may lead to deterioration, damage and cracking of the structures built on such soils. Thus, many investigations and attempts were conducted for determining swelling pressure of expansive soils. This paper presents a review of experimental and empirical methods for predicting swelling pressure. The paper further assesses their ability to predict the swelling pressure of expansive soils based on available experimental data.
