This　study　aimed　to　improve　the　rejuvenation　quality　of　aged　styrene-butadiene-styrene　(SBS)　modified　bitumen　mixture　(PmBM)　by　employing　composite　rejuvenation　through　the　synergistic　application　of　various　active-flexible　rejuvenators　(AFRs)　featuring　distinct　molecular　structures　with　aromatic　oil　(AO).　By　comparing　with　the　mixture　rejuvenated　solely　by　AO,　the　impact　of　different　AFRs　on　the　pavement　performance　of　aged　PmBM　as　well　as　its　aging　resistance　after　rejuvenation　was　explored.　The　results　demonstrated　that,　in　comparison　to　the　mixture　rejuvenated　solely　by　AO,　the　incorporation　of　AFRs　considerably　enhanced　the　high-temperature　deformation　resistance,　low-temperature　crack　resistance,　fatigue　durability,　and　water　damage　resistance　of　the　rejuvenated　PmBM.　And　these　properties　were　restored　to　levels　close　to　or　even　surpassing　those　of　fresh　mixtures.　Compared　with　sole　AO　application,　AFRs　demonstrated　superior　performance　by　effectively　restoring　the　cross-linking　structures　of　degraded　SBS　within　the　bitumen,　while　concurrently　enhancing　interfacial　adhesion　between　the　rejuvenated　bitumen　binders　and　the　granite　aggregates.　These　synergistic　effects　considerably　improved　the　structural　integrity　of　rejuvenated　PmBMs.　Moreover,　the　results　of　the　thermal　aging　showed　that　the　deterioration　degree　in　pavement　performance　after　aging　was　considerably　lower　for　the　(AFRs+AO)　rejuvenated　PmBMs　compared　to　those　rejuvenated　solely　with　AO.　The　possible　reason　is　that　AFRs　enhances　the　thermal　aging　resistance　of　the　rejuvenated　PmB　by　reconstructing　the　cross-linking　structure　of　degraded　SBS　within　the　bitumen.　The　study　reveals　that　during　the　rejuvenation　process　of　aged　PmBMs,　it　is　particularly　crucial　to　prioritize　and　effectively　restore　the　cross-linking　structures　of　degraded　SBS　within　them.　Additionally,　when　optimizing　the　molecular　structure　of　AFRs　in　subsequent　study,　it　is　imperative　to　consider　the　sensitivity　of　the　molecular　structure　of　AFRs　to　aging　factors,　so　as　to　ensure　the　durability　of　the　rejuvenated　PmBMs.
