摘要：

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