Stabilization of expansive clays with sulfonated oil is an electrochemical process that develops over time and whose progress depends on the environmental conditions in the field. This phenomenon was studied by mean of an experimental analysis of three types of expansive clay treated with sulfonated oil. To simulate the environmental conditions, these clays were subjected to UV radiation in an accelerated aging chamber. Once obtained the programmed aging period, plasticity limits of soils allowed determining the influence of aging and concentration of sulfonated oil on the properties of expansive clays. Results revealed that the final plasticity and hence the swelling potential of the material depends on the period of exposure and the concentration of sulfonated oil. Finally, it is suggested to adopt the methodology used in this study to determine the concentration of sulfonated oil, which is a function of the type of clay.
