Stability Marshall of Porous Asphalt Mixed with Waste Polyethylene Terephthalate (PET) and Modified Asbuton

Abstract

The stability of a porous asphalt mixture, including plastic waste, will be investigated in this study. In this study, plastic waste is used as an addition to improve the performance of the porous asphalt mixture. In the lab, this research is experimental. The test object without plastic waste was used as a comparison, and the variables of this study were the porous asphalt mixture utilizing plastic waste in amounts as much as 0.5%, 1.0%, 1.5%, 2.0%, and 2.5%. The results showed that the porous asphalt mixture's stability value containing plastic waste increased by 0.5%, 1.0%, 1.5%, and 2.0% compared to the porous asphalt mixture's stability value without plastic waste, which was 25.50%, 13.84%, 22.42%, and 27.40%, respectively. However, the stability value decreased from 2.0% plastic waste to 2.5% or 26.57%. Therefore, according to the study's findings and the resulting stability value, the ideal level of plastic trash is 2.0%.
