Roads designers are often faced with the challenge to design a stable solid foundation on top of Sabkha soil, which has high salt content, very low bearing capacity and loosing of its strength upon wetting.  Roads constructed on this type of soil are mainly facing problems of settlement due traffic loads and very low bearing capacity of Sabkha soft soil. This type of soil need to be stabilized using one of the stabilization techniques. The aim of this paper is study and evaluate the sabkha soil problem, which exist in North-West of Libya, where the main road connecting Libya with Tunis passed. This paper illustrates the results of using Cement Kiln Dust (CKD) in Sabkha soil stabilization.  The results show a considerable improvement of sabkha soil properties based on tests conducted specially CBR values.
