 ABSTRACT

Today, due to the increasing population and also development of construction industry, having sufficient knowledge and information about the various methods of improving the current surface soils for use in various construction projects is an essential issue for a Geotechnical Engineer. The technology for soil improvement is one of the most trustable and practical ways. It is also economically viable to increase the resistance of soil, soil strength, soil permeability, as well as to limit water absorption, control soil erosion, losing water, and soil settlement. A new liquid polymer soil stabilizer, which was developed for use as a means of stabilization treatment of soil known as SS299, was examined in this study. In order to understand the effects of SS299 on the stabilization of Laterite soil, laboratory tests on the unconfined compressive strength and shear strength of untreated and treated soil specimens were performed. The results indicated that SS299 soil stabilizer is able to significantly increase the unconfined compression strength and shear strength of Laterite soil. The unconfined compression strength increased with the duration of curing time, the variation mainly occurring in the first 7 days. Also the result indicated that this stabilizer is worth popularizing for practical projects such as road construction, backfilling, erosion control and for slope stability.
