Vamsi Krishna Kommu Suresh Journal on Civil Engineering 2249 - 0779 6 4 44 54 Modulus of Elasticity (Es), Permeability (k), CBR, UCS(qu) In general, the clayey soils reduces the enactment and lifetime of Civil Engineering structures, causing problems due to their low load carrying capacity. The Rapid growth of industries produces hazardous waste materials which act as a pollutant that affect the ecological system of the environment. Several researchers have used many additives to stabilize the soil as economical. Here, the stone dust has been used in the present study which possesses high calcium content. In this research, the effect of various sizes (5mm, 3mm, <75μ) of Stone dust with different proportions (5%, 7.5%, 10%, 12.5% and 15%) for untreated and treated soils were studied using direct shear, permeability, UCS (qu) and CBR tests. Also the modulus of elasticity of various soil mixes for sub-grade and sub-base have been determined. From the test results it has been concluded that the strength of the soil has been improved and there is a decrease in the permeability with the increase in the addition of stone dust.
