Expensive soils denote clayey soils that not only possess the tendency to increase or decrease in volume (compressibility) due to that, shear strength varies and when the prevailing moisture condition is allowed to change but also measure of the ability of a soil media to support the formation of a magnetic field within itself (permeability). Such change of moisture content of these soils can emanate from rains, floods or leakage of sewer lines. The response of expensive soil in form of compressibility and permeability due to change moisture content is frequently expressed superficially as heaving, settlement and piping (flow in stream lines) of lightly loaded geotechnical structures such as pavements, railways, roadways, channel and foundations or reservoir lining. This thesis is an experimental study evaluating the effect of robosand on permeability and shear strength of expansive soil. The initial phase of the experimental program includes the study of the effect of robosand on MDD (Maximum Dry Density) and optimum moisture content (OMC) with different percentages (by dry weight of the soil) and Specific gravity. The second phase of the experimental program focuses on Permeability and shear strength characteristics of the soil. In addition to UCS tests were performed to study the effects of nano-chemical on unconfined compressive strength of tested soil. Test results indicated that addition of robosand increased the permeability and shear strength of the soft soil with increasing robosand with respective percentages. This project ventures to find the feasibility of using a Nano chemical as stabilizer for ground improvement and to find an optimum dosage of the stabilizer which ensures maximum strength, controlling permeability characteristics. Different dosages of robosand will be added into the soil samples collected. The compaction and unconfined compression (UCS) tests are to be conducted, followed by consolidation and permeability test to determine the soil characteristics of controlling permeability and increasing shear strength.
