Due　to　the　temperature　changes　caused　by　seasonal　changes　and　extreme　weather,　asphalt　pavement　suffers　from　rutting,　cracking,　and　other　damage.　With　commonly　used　pavement　additives,　the　high-temperature　performance　and　the　low-temperature　performance　of　asphalt　pavement　show　opposite　trends,　with　related　research　endeavoring　to　find　a　balance　between　the　two.　In　this　study,　a　dual-phase-change　material　(DPCM)　with　both　high-　and　low-temperature　effects　was　prepared.　The　chemical　stability　and　rheological　properties　of　modified　asphalt　binders　were　characterized　using　Fourier　transform　infrared　spectroscopy　(FTIR)　and　a　dynamic　shear　rheometer　(DSR).　Temperature　control　tests　of　the　DPCM-modified　asphalt　binders　were　carried　out　with　an　indoor　simulation　device.　The　results　show　that　the　DPCMs　could　improve　the　rutting　resistance　of　the　asphalt　binders　at　a　high　temperature,　but　the　fatigue　performance　of　the　modified　asphalt　binder　with　different　DPCM　contents　was　reduced.　The　FTIR　results　showed　that　no　chemical　reaction　occurred　in　the　mixing　of　the　asphalt　binder　and　the　DPCM.　In　the　indoor　simulation　temperature　control　test,　the　40%　DPCM-content-modified　asphalt　binder　reduced　the　high-temperature　extreme　value　by　4.2　degrees　C　and　increased　the　low-temperature　extreme　value　by　2.5　degrees　C,　showing　a　good　temperature　control　effect　and　practical　application　value.
