SBS　modified　asphalt　(SBSMA)　pavements　have　gained　popularity　worldwide　due　to　their　prominent　performance.　However,　its　maintenance　and　reconstruction　projects　will　produce　a　large　amount　of　reclaimed　asphalt　pavement　(RAP)　during　the　long-term　service　of　asphalt　pavement.　Adding　rejuvenators　products　is　a　common　method　to　recycling　RAP.　However,　conventional　rejuvenators　are　typical　component　regulators　applicable　to　recycling　unmodified　asphalt,　while　there　is　a　poor　regeneration　effect　for　the　aged　SBS　modified　asphalt　(ASBSMA),　because　it　cannot　repair　the　degraded　SBS　polymer.　Fortunately,　reactive　rejuvenator　(RR)　has　achieved　this　breakthrough　based　on　the　research　findings　in　recent　years.　It　contains　special　compounds　that　have　the　ability　to　repair　the　degraded　SBS.　The　vital　questions　to　be　investigated　in　the　present　review　are　how　the　four　current　systems　of　RR　(epoxy　system,　isocyanate　system,　compound　system　and　polymer　system)　affect　ASBSMA＇s　properties　and　how　well　does　its　regeneration　effect.　Existing　research　indicated　that　RRs　are　favorable　for　the　regeneration　of　A-SBSMA　and　have　their　respective　characteristics.　This　review　summaries　various　RR　different　regeneration　mechanism,　and　analyzed　its　effects　on　physical　properties,　rheological　properties,　high　and　low　temperature　properties,　and　microscopic　characteristics　of　A-SBSMA.　Although　research　on　RR　is　still　in　its　infancy　with　a　limited　number　of　relevant　studies,　they　show　an　excellent　regeneration　effect　for　A-SBSMA　and　hold　a　promising　prospect.　Overall,　this　review　provides　information　on　the　feasibility　of　using　RR　as　a　sustainable　SBSMA　rejuvenator　to　promote　conserving　resources　and　reusing　RAP.
