摘要：

Rutting　is　one　of　the　common　distress　of　asphalt　pavement.　The　addition　of　modifier　can　improve　the　high　temperature　performance　of　asphalt　binder　but　the　fatigue　resistance　is　the　main　concern　of　high　modulus　asphalt　binder.　This　paper　uses　the　50#　neat　binder　and　mixes　it　with　different　modifiers　to　get　two　kinds　of　high　modulus　asphalt　binder　named　50#　+　RA　and　50#　+　PR.　Take　frequency　sweep　test　and　linear　amplitude　sweep　test　based　on　dynamic　shear　rheometer　to　predict　the　fatigue　life　of　asphalt　binder.　The　experimental　results　show　that　high　modulus　asphalt　binders　show　distinguished　fatigue　performance　with　the　addition　of　different　modifiers.　©　2017　Taylor　&　Francis　Group,　London.
