Abstract：To enhance the road performance,water stability,and the high temperature stability of Asphalt Concrete,a study was conducted to modify Asphalt Concrete AC-16 with PET(Polyethylene Terephthalate)plastic particles.Considering the climate conditions of Jiangsu and Anhui(subtropical and temperate zones),an optimal mix ratio was determined.The effects of four different dosages(0％,2％,4％,and 6％of the mass of the Asphalt Concrete)of PET particles on water stability and high-temperature stability(rutting resistance)of Ac-16 were examined through freeze-thaw split test,immersion Marshall Test,and rutting test to identify a suitable dosage.The results indicate that the addition of PET plastic particles enhances the road performance of the Asphalt Concrete.Based on the foundational tests and practical engineering,4％PET plastic particles are recommended as the most suitable content.
