SBS　modified　asphalt　is　an　important　material　to　improve　the　quality　of　high-grade　pavements　and　airport　runways,　it　will　deteriorate　during　the　service　life　due　to　a　combination　of　environmental　factors　leading　to　pavement　disease　which　triggers　the　maintenance　and　reconstruction.　In　this　process,　an　amount　of　reclaimed　asphalt　pavement　(RAP)　will　be　produced.　For　environment　protection　and　resource　reservation,　RAP　is　usually　regenerated　by　a　rejuvenator.　In　this　paper,　reactive　rejuvenators　were　prepared　by　epoxy　compounds　for　regenerating　aged　SBS　modified　asphalt　(A-SBSMA),　and　the　changes　in　physical　properties,　rheological　properties,　chemical　structure,　and　microscopic　morphology　of　the　regeneration　of　A-SBSMA　before　and　after　were　investigated　to　evaluate　the　regeneration　effect.　Compared　with　traditional　rejuvenators,　the　significant　effect　of　reactive　rejuvenators　on　the　recovery　of　physical　properties　and　rheological　properties　of　A-SBSMA.　By　FTIR　and　microscopic　morphology　analysis,　reactive　rejuvenator　can　better　recover　the　functional　group　species,　broken　SBS　molecular　structure,　and　network　structure　of　A-SBSMA.　　©　2023　ASCE.
