摘要：

In　order　to　get　a　better　evaluation　on　high-temperature　feature　of　asphalt　binder,　conducted　on　dynamic　shear　rheometer　(DSR)　and　based　on　the　oscillation　test　to　fix　the　asphalt　PG　high-temperature　grade,　multiple　stress　creep　recovery　(MSCR)　test　was　employed　to　contrastively　evaluate　the　high-temperature　rutting　potential　of　neat　binder　and　SBS　modified　binder.　Test　results　indicate　that　the　G*/sinδ　determined　from　the　oscillation　test　in　the　existing　specification　is　well　applied　for　neat　asphalt　but　really　does　not　work　for　modified　asphalt,　whereas　the　recovery　percent　R　determined　from　the　MSCR　test　is　able　to　characterize　the　delay　elasticity　of　modified　asphalt　well,　and　the　nonrecoverable　compliance　Jnr　measured　in　MSCR　test　is　developed　as　a　replacement　for　the　G*/sinδ　to　evaluate　the　high-temperature　rutting　properties　for　binders.　Additionally,　the　SBS　modified　binder　is　found　more　sensitive　to　the　stress　levels　than　the　neat　binder.
