Sustainable Potentials of Plastics Waste-cement Kiln Dust Blends on Strength Properties of Subbase Soil

There are large deposits of waste materials from various industrial or building activity all over the world. Out this enormous quantity waste, a little amount gets recycled, while rest is dumped in vulnerable places. This paper examines potential use subbase, including recycled chips derived polyethylene terephthalate plastics and cement kiln dust resulting Portland industry as by-product. Samples were formed by blending fractions 0, 4, 6, 8% with without 3% (CKD) required weight subbase soil. The influence terms strength was evaluated using CBR values, which exhibited descending values increasing contents. While addition CKD significantly enlarged values. Based on 4% blend commended for layer roads construction.
