This paper provides a systematic review of the current research status and application prospects of waste plastic modified asphalt (WPMA) technology. It begins by outlining the severity of global plastic pollution and the urgency of recycling waste plastics, emphasizing that its application in asphalt modification represents an effective pathway for high-value utilization. The article not only presents the current state of waste plastic recycling but also focuses on analyzing three preparation processes: wet process, dry process, and wet-dry composite process, along with a comparative evaluation of their advantages and disadvantages.
