Abstract

The ability of expansive soils to swell and shrink causes damage to the structures, especially for light buildings and pavements. Generally, swells and shrinks this expansive soil due to changes in water content in the active zone. This paper is a study about behavior of swelling pressure of expansive soil within the active zone. This research using undisturbed samples of soil that was taken from Surabaya Citraland. The experiment of swelling pressure was started from the samples with natural water content, furthermore a series of swelling pressure experiments is performed for a series of samples that was added or subtracted by some water to increase or decrease its water content. Repeated swelling pressure experiments were also performed for a sample that has undergone a drying-wetting cycle repetition. The experiment shows that swelling pressure decrease with increasing of water content of soil, in other side the swelling pressure of expansive soil remain constant after sixth repetition of swelling pressure experiment.
