Currently　the　linear　amplitude　sweep　(LAS)　test　is　one　of　the　main　fatigue　protocols　to　estimate　the　fatigue　resistance　of　asphalt　binder.　In　past　10-years,　several　data　interpretation　approaches　have　been　developed　for　the　LAS-based　binder　fatigue　modeling.　The　objective　of　this　paper　is　to　compare　the　currently　available　analytical　approaches　for　the　data　interpretation　of　LAS　test　and　further　investigate　the　potential　links　between　the　different　LAS-based　fatigue　evaluations　of　asphalt　binders.　Totally　20　types　of　unmodified　and　modified　asphalt　binders　are　selected　in　this　study,　which　actually　cover　35　sample　conditions　under　different　aging　and　temperature　levels.　Experimental　and　analysis　results　indicate　that　the　full　fatigue　performance　of　asphalt　binder　can　be　characterized　from　with　the　S-VECD　&　G(R)　approach.　The　failure　property　in　LAS　test　is　also　well　correlated　to　the　binder　fatigue　life　simulation　and　thus　can　be　utilized　to　more　efficiently　distinguish　the　binder　fatigue　resistance.　Furthermore,　the　performance　predictive　accuracy　of　AASHTO　TP101　specification　method　is　strongly　dependent　on　the　selected　failure　definition.　Taking　the　artificial　failure　definition　of　35%　reduction　in　|G*|.sin　delta　largely　underestimates　the　binder　fatigue　life　when　compared　to　the　S-VECD　&　G(R)　approach.　However,　when　a　material-dependent　failure　definition　of　peak　stress　is　alternatively　employed　in　specification　method,　the　correlation　of　the　predictive　binder　fatigue　life　between　the　two　analytical　approaches　is　significantly　improved　and　a　linear　relationship　is　additionally　found　between　the　S-VECD　&　G(R)　approach　and　specification　method.　Therefore,　it　is　recommended　that　when　only　the　standard　LAS　test　with　one　loading　rate　is　available　in　practice,　the　peak　stress　failure　definition　should　be　used　in　AASHTO　TP101　specification　method　to　provide　relatively　accurate　fatigue　performance　estimation　of　asphalt　binder.
