The　damping　property　of　asphalt　is　essential　in　reducing　pavement　vibration　and　noise.　This　study　mainly　presents　the　damping　property　of　the　styrene-butadiene-styrene　(SBS)　modified　asphalt　under　a　wide　temperature　range　and　aging.　The　materials　used　11　total　combinations　of　the　base　asphalt,　three　modifiers　(SBS,　crumb　rubber　[CR],　and　polythene),　and　three　additives　(hydrotalcite,　crosslinker,　and　plasticizer).　The　loss　factor　(LF)　was　first　measured　by　the　dynamic　shear　rheometer.　Then,　the　four　parameters,　namely　glass　transition　temperature　(Tg),　the　maximum　loss　factor　(LFmax),　effective　temperature　range　of　damping　(ΔT0.7),　and　area　under　the　loss　factor　curve　(TA),　were　used　to　evaluate　the　damping　characteristics　of　asphalt　at　a　wide　temperature　range.　Based　on　this,　the　damping　property　of　the　base,　SBS,　and　CR　of　aged　asphalt　is　analyzed.　The　results　show　that　in　the　medium-　and　high-temperature　regions,　the　crosslinker　and　plasticizer　can　effectively　improve　the　temperature　sensitivity　of　SBS　modified　(SM)　asphalt　and　the　damping　property.　Adding　plasticizer　and　crosslinker　at　the　same　time　improves　the　damping　property　of　asphalt　most　significantly.　In　the　middle-low　temperature　region,　both　the　SM　asphalt　and　CR　modified　asphalt　have　a　poor　damping　property,　and　the　crosslinker　and　plasticizer　have　no　apparent　effect　on　the　improvement　of　SM　asphalt.　The　damping　property　of　SM　asphalt　decreases　more　slowly　than　that　of　base　asphalt　after　aging,　and　it　still　has　a　good　damping　property.　The　outlined　research　results　show　that　SM　asphalt　has　a　good　damping　capacity　of　pavement　at　medium-　and　high-temperature　ranges　and　after　aging,　which　can　assist　in　developing　a　sustainable　solution　to　extend　the　service　life　of　pavement　without　increasing　the　thickness　of　pavement.　©　2022　by　ASTM　International
