Abstract

Many ground improvement techniques have been evolved in the past decade in order to reduce the potential of severity of the expansive soils. Out of those techniques, soil stabilization is the most effective technique. This paper presents results of the investigation carried out to stabilize an expansive soil using RBI grade 81 stabilizer. Free swell index, CBR and SEM analysis were carried out on both untreated and treated soils. There was a considerable reduction in swell potential and an increase in the strength of the soil with the addition of stabilizer.
