Abstract

Polyethylene terephthalate (PET) waste is a major contributor to global environmental pollution, and if it is not well managed, it can seriously risk both environmental and human health. Chemical processing of PET offers a promising method to reduce these negative effects. Recent studies have investigated the chemically–processed of PET waste products in bituminous binder and asphalt mixture modifying. So, this paper aims to review the recent development of the incorporation of PET waste degradation products into bituminous binders and asphalt mixtures. The systematic literature review (SLR) was conducted utilizing the Web of Science (WoS) database. Reference papers were selected based on specific keywords and the Preferred Reporting Items for Systematic Reviews and Meta–Analyses (PRISMA) guidelines. The result shows the current research on PET waste preparation methods, synthesis, mixing method, and effects on bituminous binder characteristics and asphalt mixture. To create the “success story” of the implementation of PET waste degradation products in bituminous binder and asphalt mixture, some recommendations for future research are also provided in this paper.
