This paper deals with the innovation of road construction materials by the use of polyethylene terephthalate (PET) as asphalt mixtures. The PET was obtained from plastic bottles waste. The purpose of this research is to investigate the effects of the PET on Marshall parameters on asphalt concrete pavement. The wet method is used in this research. It means that PET plastic material is directly mixed into asphalt when the asphalt is heated, then aggregates are added. In this research, asphalt with penetration of 60/70 is used. Its optimum asphalt content (OAC) is 5.7 percent while The percentages of the added PET are 3 percent, 4 percent, 5 percent, 6 percent, and 7 percent of the asphalt by weight. The results show that the addition of PET plastic waste into the mixture has a significant positive effect on the Marshall parameters of asphalt concrete pavement. The addition of PET waste has been able to increase the value of other Marshall parameters, including Voids in Mix (VIM), Voids in Mineral Aggregates (VMA), Voids Filled with Asphalt (VFA), Flow, and Marshall Quotient (MQ). This research result will contribute to a significant outcome in emerging a sustainable material for road infrastructure.
