ABSTRACT

Stabilization of expansive clay soils treated with Lime is an effective method, its aim being to diminish, as much as possible, volumetric changes when these types of soils are in contact with water. However, in the curing stage, whose objective is to maintain hydrated the mixture soil-lime for a given time, it is generally recommended to do it for eight or more days, thus, this method is commonly discarded. Because of the above, in this work, the study of curing time of stabilized expansive soils with lime is reported. Different water contents and times of initial curing were considered for determining the optimum curing time. Clearly, this will reduce costs and maybe will be more attractive its application.

Keywords: Curing, expansive clays, soil stabilization, lime, soil treatment, clays, expansive soils, lime stabilization.
