To build the structures on allotted site or make use of locally available soil for overall economy of the project, stabilization of clayey or clayey silty soil needs to be done. Soil stabilization is done by various methods like mechanical stabilization cement stabilization, lime stabilization, chemical stabilization, thermal stabilization, electrical stabilization & consolidation stabilization etc. Chemical stabilization is done by making use of material like lime, fly ash, cement, sodium chloride, calcium chloride, magnesium chloride etc. Soil stabilization of clayey soil is also done by using lime kiln dust, cement kiln dust, brick kiln dust, stone quarry dust etc. A Thermal Plant namely Nabha Thermal Plant has been installed and made operational in the year 2014 by Punjab State in Village Nalash, Tehsil Rajpura District Patiala. While constructing Thermal Plant, earth to the tune of 6 lac cum had been excavated for making lake and had been dumped near the plant in the form of heaps which has occupied about 100 acres of land. Consequently this heavy chunk of land has turned into desert like situation and cannot be used for cultivation or other purposes till the dumped material is disposed off. Many infrastructure projects like Special Railway Project from Ludhiana to Kolkata called Eastern Dedicated Freight Corridor, Rajpura –chandigarh line and doubling of Rajpura-Bathinda lines have been announced by Govt, of India and construction works of two out of three have already been commenced recently. These projects require heavy quantum of earth for making embankments. There is scarcity of earth in this area due to high fertility of land. An effort has been made by the researcher to utilise this surplus lying earth for above civil engg. projects involving earth work in embankment by blending it with locally available sandy soil. This may save cost and create environment friendly area by converting the land again into green belt after utilisation of this surplus earth. Effect of mixing local sandy soil with clayey soil on Strain modulus (load deformation characteristics of soil at second loading cycle between 30% & 70% of maximum normal stress denoted as Ev2) has been studied in this report. Field testing to study strain modulus on trail bed of varying thicknesses has been done. Results show that strain modulus values have increased.. Safety of any structure depends upon bearing capacity of the soil and its shearing strength. Weak soils like clayey, clayey silty soils exhibit lower bearing capacity, low shear strength and high settlements. Therefore to build the structures on allotted site or make use of locally available soil, stabilization of clayey or clayey silty soil needs to be done. Much literature is available for improving index/engineering properties of soil particularly for Improving index properties, CBR ,MDD, and shear strength but limited literature is available for mechanical stabilization i.e. to improve strain modulus (EV2) values by blending the locally available materials. The available clayey soil (CH) to the tune of 6 lacs cum has been lying surplus to the requirement of Nabha Thermal Plant and has occupied a space of about 100 acres and efforts to utilize this surplus lying earth and make this fertile land available for agriculture or other purposes have not been made so far. Purpose of this research is to study the effect of sandy soil on strain modulus (EV2) of soil when mixed clayey soil of CH category.
