Abstract

From the perspective of geotechnical engineering, increasing the stability of earth slopes into three general categories, mechanical methods, soil reinforcement and chemical methods, are divided. The geotechnical engineering researchers have been considered on the soil behavior modification to aid additives that is classified in chemical methods, always as one of the most effective methods for increasing the stability of the earth slopes. In this study, the effect of adding four materials sodium chloride, calcium chloride, lime and mixed of lime and bagasse ash at 5, 7.5 and 10 wt% during the curing period of 7 and 21 days, were studied. The results of this study showed that sodium chloride reduces the stability of earth slopes, and calcium chloride, lime and  mixed of lime and bagasse ash enhance the stability of earth slopes. The results also showed that the curing period of 21 days compared to 7-day curing period is more effective in increasing or decreasing the stability of earth slopes.
