Different soils behave differently to the loads subjected on them. To improve the strength parameters of soil, various additive materials have been suggested over the time. The main focus of this research was to enhance the strength of mountainous clayey subgrade & to get an optimum amount of Soil-Cement-Jute mix. For a fact Jute acts as a reinforcing material when added to subgrade. As mountainous clay shows high shrinkage, swell characteristics & low bearing capacity especially under sub-grade, therefore, there's a requirement to enhance the strength characteristics of soil. The main focus of this research was to improve the strength characteristics of subgrade. The tests performed in laboratory was Pycnometer test for relative density, Casagrande’s test for liquid limit, plastic limit test, Standard proctor test for determination of OMC & MDD & modified proctor test. Proportion of the 6mm Jute used was 0.4, 0.7, 1.0, 2.0 & 4.0 % & proportion of cement was 1, 3, 5, and 7% by wright of sample. The optimum value of cement and 6mm jute fibre was found to be 5% and 0.4% respectively. The CBR value was found peak at 2% cement + 0.4% Jute fibre (6mm) combination. From the results it had been verified that 0.4% Jute content is more economical than 5% cement content.
