Aging　takes　place　in　asphalt　binder　materials　during　the　construction　and　service　life　of　asphalt　pavement　and　has　a　significant　effect　on　their　performance.　The　development　of　anti-aging　technology　is　of　great　significance　to　improve　the　durability　of　asphalt　pavement.　In　this　study,　four　kinds　of　anti-aging　modified　asphalt　binders　were　prepared.　The　rheological　properties　of　different　modified　asphalt　binders　before　and　after　aging　were　tested　by　dynamic　shear　rheometer　(DSR).　The　chemical　properties　of　different　modified　asphalt　binders　after　aging　were　analyzed　by　Fourier　transform　infrared　spectrometer　(FTIR).　Based　on　these,　the　mechanism　of　anti-aging　was　analyzed,　and　a　more　suitable　high-performance　anti-aging　additive　was　selected.　The　results　showed　that　the　addition　of　1#,　2#　and　4#　anti-aging　additives　improved　the　properties　of　unaged　asphalt　binder.　The　addition　of　2#　anti-aging　additive　(1%)　has　the　best　resistance　to　the　increase　of　complex　modulus,　the　reduction　of　viscous　flow　characteristics　and　cracking　risk　caused　by　aging.　It　can　be　attributed　to　their　ability　to　inhibit　the　formation　of　carbonyl　and　sulfoxide　groups　in　the　oxidation　reaction　of　asphalt　binder　aging.　2#　anti-aging　additive　can　effectively　slow　down　the　aging　rate　of　asphalt　binder,　and　has　a　strong　applicability　in　the　study　of　asphalt　binder　anti-aging　technology.　©　2022　the　Author(s).
