Abstract：

This　paper　first　presents　the　evaluation　of　damping　performance　of　four　types　of　asphalts:　base,　non-　polymer　modified,　polymer　modified,　and　stress-absorbing　modified　asphalts　using　the　temperature　spectra　of　the　loss　factor　(LF)　based　on　dynamic　shear　rheometer.　The　results　showed　that　the　styrene-butadiene-styrene　(SBS)　and　crumb　rubber　(CR)　were　the　optimal　polymers　to　improve　the　damping　performance　of　the　base　asphalt　based　on　four　criteria.　The　damping　performance　of　SBS　and　CR　modified　asphalts　was　further　improved　by　the　proper　addition　of　crosslinker　and　plasticizer,　and　the　SBS/CR　compound　modified　asphalts　held　good　damping　performance　for　a　complementary　effect.　A　high　damping　capacity　of　stress-absorbing　modified　asphalts　was　observed.　©　2018　Elsevier　Ltd
