This paper describes a study on silty soil stabilization to improve its engineering properties. To evaluate the strength characteristics of stabilized silty soil, laboratory investigation on early strength gain of the stabilized soil was conducted to formulate a suitable and economical mix design that could be effectively used for the silty soil stabilization. To achieve such purpose, the study examined the effect of Nano-Clay on the California Bearing Ratio and unconfined compressive strength of silt. The results showed that of the Nano-Clay increased the strength of silt. The California Bearing Ratio of the soil and unconfined compressive strength were found to increase significantly with increasing in the Nano-Clay. It could be summarized that the Nano-Clay particles in the vicinity of moisture can cause soil stabilization by fastening the particles together.
