Abstract: This research is to study the relationship between the value of factor of safety in slope stability and other factors influencing that value for the road embankment that is light weight material standing on soft clay foundation. It is aimed to develop set of design charts for designing the slope stability of the road embankment containing light weight material on soft clay foundation. The light weight material studied in this research is rice husk ash with sand and cement. Rice husk ash was mixed with sand at the proportions of 100:0 and 60:40 and with cement at the percentage of 0 and 3 by weight of dry soil. Then, the specimens were tested by compacting with Modified Proctor method and direct shear test. The test result is added for the analysis which were done upon the analysis model containing the varied combinations of the following factors such as shear strength of soft clay, thickness of soft clay layer, width and height of embankment. In this analysis, the computer program, so called "SLOPE/W", using Simplified Bishop's method was used as a calculation tool.Results from this research showed that shear strength of soft clay and height of embankment significantly influenced the factor of safety in slope stability. The factor of safety increased as the shear strength of soft clay increased. In contrary, the factor of safety decreased as the height of embankment increased. Moreover, when the thickness of soft clay layer increased, the factor of safety gradually decreased and then remained steady.The width of embankment did not effect the factor of safety if the thickness of soft clay layer is thin. If the thickness of soft clay layer is thick, the factor of safety slightly decreased when the width of embankment increased. Finally, it could be concluded that the result showed in this research could be effectively used in designing the road embankment when the light weight material was laying on soft clay foundation.
