ABSTRACT
The present experimental series evaluated the combined effect of lime and fiber addition on the shear strength response of locally available soil. A locally available soil (LAS) in Palaj village of Gandhinagar, classified as clayey sand (SC), was selected for this study. Initially, a series of unconfined compression (UC) tests was performed on hydrated lime-treated LAS specimens cured for seven days at different lime content. Subsequently, a series of UC tests were performed on LAS stabilized with different amounts of polypropylene fibers. It was observed from the initial series that after 2% lime, the increase in shear strength became less significant, whereas, addition of 0.15% of fibers resulted in maximum strength. Further, a series of UC tests were performed on lime-treated LAS specimens reinforced with 0.15% of polypropylene fibers at different lime content (0%, 2% and 6%). It was observed that the inclusion of fibers resulted in an increase in the strength and ductility of lime-treated LAS specimens.
