Abstract
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.
期刊介绍：
Periodica Polytechnica Civil Engineering is a peer reviewed scientific journal published by the Faculty of Civil Engineering of the Budapest University of Technology and Economics. It was founded in 1957. Publication frequency: quarterly.
Periodica Polytechnica Civil Engineering publishes both research and application oriented papers, in the area of civil engineering.
The main scope of the journal is to publish original research articles in the wide field of civil engineering, including geodesy and surveying, construction materials and engineering geology, photogrammetry and geoinformatics, geotechnics, structural engineering, architectural engineering, structural mechanics, highway and railway engineering, hydraulic and water resources engineering, sanitary and environmental engineering, engineering optimisation and history of civil engineering. The journal is abstracted by several international databases, see the main page.
