Abstract: Most of the constructed structures such as roadways, railways, water reservoirs etc. requires huge amount of soil. In most areas borrow earth is not easily available and has to be transported from a long distance. One way to overcome these problems in soils is to stabilize with admixtures; this is because such a stabilization procedure improves engineering properties of the soil such as volume stability, strength and durability. The main objective is to improve the characteristics of the available soil and make the soil capable of carrying load and to increase strength of the soil. In this study, the clay soil is modified or stabilized with powdered glass. Waste broken glass is a non- biodegradable material, which creates environmental related problem therefore its use in sub grade soil modification, will minimize the problem. In the present research, used waste glass powder i.e. stabilizer is obtained from various glass cutting and fitting shops, Gwalior, Madhya Pradesh and soil samples which are modified obtained from in between the area of Gole ka Mandir and Bada Gaon, Gwalior, Madhya Pradesh. Selecting optimum percentage i.e. 15% of cement as base by weight of soil sample mixed with various proportions of waste glass powder i.e. 1%, 2%, 5%, 10% and 15%., also by weight of soil sample and the modified soil is then studied. Various cement properties, glass properties along with Soil properties viz atterberg’s limits, plasticity index, maximum dry density (MDD), optimum moisture content (OMC), California bearing ratio (CBR), Direct Shear test on a number of soil samples mixed with mixture of cement and glass powder (15 % cement & 1%-15% of glass powder) were studied and results with the non-stabilised soil was compared. Results of various tests demonstrated that the inclusion of cement and glass powder in soil with appropriate proportion improved strength and properties of soils.

Keywords: Atterberg limits, PL, LL, MDD, OMC, CBR, Direct Shear.
