The purpose of this study is to investigate the usability of the waste material containing PET in the dense bituminous mix as a bitumen modifier. Considering their deterministic role in the performance of polymer-modified bitumen blends, the study was focused on the effects of the modifier (PET) content, on the Marshall stability, flow, Marshall Quotient, air void in mix and resilient modulus. The samples were prepared by mixing the dense graded aggregates (nominal size 14mm, named ACW14) with 80/100 penetration grade bitumen and a series of different percentages of PET by weight of bitumen. It can be said that PET modified bituminous mixes provide better resistance against permanent deformations due to their high stability and it contributes to recirculation of plastic wastes as well as to protection of the environment.
