To　solve　the　problems　on　resource　utilization　and　environmental　pollution　of　waste　concrete　and　waste　polypropylene　(PP)　plastics,　the　recycling　of　them　into　asphalt　pavement　is　a　feasible　approach.　Considering　the　high　melting　temperature　of　waste　PP,　this　study　adopted　a　thermal-and-mechanochemical　method　to　convert　waste　PP　into　high-performance　warm-mix　asphalt　modifiers　(PPMs)　through　the　hybrid　use　of　dicumyl　peroxide　(DCP),　maleic　anhydride　(MAH),　and　epoxidized　soybean　oil　(ESO)　for　preparing　an　asphalt　mixture　(RCAAM)　containing　recycled　concrete　aggregate　(RCA).　For　the　prepared　RCAAM　containing　PPMs,　the　mixing　temperature　was　about　30　°C　lower　than　that　of　the　hot-mix　RCAAM　containing　untreated　PP.　Further,　the　high-temperature　property,　low-temperature　crack　resistance,　moisture-induced　damage　resistance,　and　fatigue　resistance　of　the　RCAAM　were　characterized.　The　results　indicated　that　the　maximum　flexural　strain　of　the　RCAAM　increased　by　7.8~21.4%　after　using　PPMs,　while　the　sectional　fractures　of　the　asphalt　binder　were　reduced　after　damaging　at　low　temperature.　The　use　of　ESO　in　PPMs　can　promote　the　cohesion　enhancement　of　the　asphalt　binder　and　also　improve　the　high-temperature　deformation　resistance　and　fatigue　performance　of　the　RCAAM.　Notably,　the　warm-mix　epoxidized　PPMA　mixture　worked　better　close　to　the　hot-mix　untreated　PPMA　mixture,　even　after　the　mixing　temperature　was　reduced　by　30　°C.　©　2024　by　the　authors.
