Recycling　of　waste　plastics　for　asphalt　modification　is　important　to　achieve　the　resourceful　use　of　waste　plastics　and　improve　base　asphalt　properties.　Therefore,　it　has　received　wide　attention　in　the　field　of　waste　plastics　processing　and　asphalt　pavement.　This　paper　focused　on　the　compatibility　and　the　performance　of　waste　plastic　modified　asphalt.　Current　situation　of　waste　plastics　and　its　application　in　the　field　of　asphalts　was　systematically　described.　The　characterization　and　enhancement　methods　of　compatibility　of　waste　plastic　modified　asphalt　were　summarized.　Moreover,　the　research　results　of　high　and　low　temperature　properties,　rheological,　fatigue　and　aging　properties　of　waste　plastic　modified　asphalt　were　reviewed　and　analyzed.　Comprehensive　asphalt　performance　and　the　research　status　put　forward　the　research　recommendations.　In　the　future,　the　mechanism　of　waste　plastics　used　in　asphalt　modification　should　be　clarified　through　multi-scale　methods.　The　constitutive　relationship　between　waste　plastic　structure　and　asphalt　properties　should　be　investigated.　In　addition,　low-cost　ways　to　improve　the　compatibility　and　low-temperature　performance　of　waste　plastic　modified　asphalt　should　be　identified　and　the　performance　evaluation　system　should　be　enriched　by　combining　the　characteristics　of　modified　asphalt　including　compatibility　and　aging　property.　©　2025　Chemical　Industry　Press　Co.,　Ltd..　All　rights　reserved.
