 ABSTRACT

Styrene Butadiene Rubber (SBR) polymer has been effectively used as an inexpensive, eco-friendly, reliable, and easily applied material for soil stabilization and the obtained response performance has been evaluated. The herein described method is an improvement on the traditional stabilizing agents previously used as it provides a cost effective pathway with a simple technical strategy. In particular, this research emphasizes improving the engineering properties of virgin soil by mixing it with varying percentages of liquid chemical stabilizer. The evaluation of the effectiveness and the performance of SBR as a soil stabilizer was performed in a series of laboratory tests on geotechnical soil properties such as consistency limits, compaction, direct shear, and permeability. The obtained results revealed that the addition of SBR (2.5% SBR) to the virgin soil resulted in a 17.8% increase in soil strength and a 71.9% decrease in the liquid lim 13.5% decrease in the plasticity index.

Keywords: SBR, Chemical stabilization, Geotechnical properties, direct shear test, consistency limits .
