The　objective　of　this　paper　is　to　investigate　and　compare　the　fatigue　failure　characteristics　of　neat　and　modified　asphalt　binders　using　both　cyclic　and　monotonic　loading　modes,　and　further　discuss　the　potential　possibility　of　using　the　monotonic　test　for　binder　fatigue　resistance　ranking　of　purchase　specification.　The　cyclic　linear　amplitude　sweep　(LAS)　test　(AASHTO　TP　101)　has　been　introduced　to　quantify　the　strain　at　peak　stress,　and　also　to　predict　the　strain-controlled　binder　fatigue　life　from　applying　the　simplified-viscoelastic　continuum　damage　modeling　(S-VECD)　approach.　Although　the　LAS　is　getting　acceptance,　the　mathematical　fitting　approach　is　very　complicated　and　require　advanced　curve　fitting　and　analysis　procedure.　A　simple　alternative　for　characterizing　binder　failure　properties　is　the　use　of　monotonic　loading　as　described　in　the　binder　yield　energy　test　(BYET)　and　dynamic　shear　rheometer-elastic　recovery　(DSR-ER)　test　(AASHTO　TP　123).　In　this　study　the　BYET　based　failure　strain　is　found　to　most　efficiently　correlate　to　the　LAS　based　failure　strain　and　predicted　fatigue　life.　However,　the　multiple-peak　phenomenon　observed　in　the　BYET　stress-strain　curves　of　some　of　the　complex　modified　binders　makes　it　very　difficult　to　clearly　identify　the　failure　parameters.　Results　collected　in　this　study　show　that　using　the　DSR-ER　test　results　can　be　a　good　addition　to　the　BYET　to　predict　fatigue　life　of　a　number　of　highly　modified　binders　as　estimated　from　the　complex　LAS　mathematical　procedure.　Therefore,　the　combined　use　of　the　monotonic　BYET　and　DSR-ER　tests　is　recommended　as　an　alternative　to　the　cyclic　LAS　test　for　ranking　the　fatigue　resistance　of　modified　asphalt　binders　in　routine　practice.　(C)　2017　Elsevier　Ltd.　All　rights　reserved.
