Dual-phase　change　materials　have　the　potential　to　improve　both　rutting　resistance　and　cracking　resistance　of　asphalt　pavement,　which　have　been　recognized　as　very　difficult　to　balance　for　a　long　time.　The　aim　of　this　paper　was　to　develop　a　dual-phase　change　material　which　can　be　used　to　regulate　temperature　at　high　and　low　temperature,and　verify　its　road　properties.　Six　kinds　of　composite　phase　change　materials　were　selected　according　to　the　technical　requirements　of　phase　change　materials,　and　the　latent　heat　performance,　thermal　stability　and　chemical　stability　of　different　phase　change　materials　were　studied　by　differential　scanning　calorimeter,　thermogravimetric　analysis　and　infrared　spectroscopy　analysis.　Then　the　latent　heat　performance　and　temperature　regulation　performance　of　the　six　phase　change　asphalts　were　evaluated　to　analyze　the　heat　absorption　and　release　ability　and　temperature　regulation　effect　of　different　composite　phase　change　materials　in　asphalt;the　influence　of　different　phase　change　materials　on　the　performance　of　matrix　asphalt　was　compared　through　the　study　of　viscoelastic　properties,　high　temperature　rutting　resistance,　medium　temperature　fatigue　resistance　and　low　temperature　performance　and　other　mechanical　properties　of　different　phase　change　asphalts.　Considering　the　thermal　and　mechanical　properties,　3#　and　6#　phase　change　materials　were　selected　as　raw　materials　for　the　development　of　dual-phase　change　temperature　modifying　materials　for　road　use.　The　results　indicated　that　the　optimal　content　of　3#　and　6#　phase　change　materials　is　1.3　%.　The　addition　of　dual　phase　change　materials　can　delay　the　heating/cooling　rate　of　asphalt　mixture　by　4.8　%–6.8　%　at　high　temperature　and　by　6.9　%–10.2　%　at　low　temperature.　Compared　with　ordinary　asphalt　mixture,　the　dynamic　stability　and　maximum　flexural　strain　of　dual　phase　change　asphalt　mixture　are　increased　by　27.8　%　and　0.37　%　respectively,　and　the　high　temperature　rutting　resistance　and　low　temperature　cracking　resistance　are　improved.　©　2024　Elsevier　Ltd
