Abstract


Due to rapid growth in population and urbanization, consumption of plastic is increasing day by day. Expansive soil a type of problematic soil is risky that has high compressibility, low shear strength and high permeability. In this research, expansive soil was stabilized using recycled plastic chips.  Used plastic bottles were collected and altered into plastic chips and then mixed up with expansive soil 5%, 10% and 15%. After that laboratory tests such as specific gravity and direct shear test were performed. It was seen that specific gravity was increased gradually after mixing plastic chips and shear strength was increased effectively for 15% plastic chips addition.
