In　this　study,　the　novel　long-chain　active　composite　rejuvenators　(NLCACRs)　were　composed　of　long-chain　active　rejuvenators　(LCARs)　and　aromatic　hydrocarbon　oil　(ArO).　Surface　free　energy　method　(SFE　method),　boiling　water　test　method　(BWT　method)　and　related　parameters　were　used　to　evaluate　the　effect　of　NLCACRs　on　interfacial　adhesion　between　aged　SBS　modified　asphalt　(ASBS-MA)　and　granite,　and　preliminarily　predict　the　moisture　sensitivity　of　asphalt-aggregate　system.　The　results　indicated　that　NLCACRs　could　increase　the　surface　free　energy　of　ASBS-MA,　and　the　increased　range　varied　with　the　composition　and　structure　of　NLCACRs.　The　NLCACRs　could　not　only　supplement　the　light　components　lost　by　asphalt　during　aging,　but　also　reconstruct　the　damaged　structure　of　aged　SBS,　so　they　were　more　effective　for　the　recovery　of　cohesion　work　of　ASBS-MA.　NLCACRs　could　significantly　increase　the　interfacial　adhesion　between　ASBS-MA　and　acid　granite,　and　decrease　the　moisture　sensitivity　of　rejuvenated　SBS　modified　asphalt　(RSBS-MA)-granite　system.　And　the　results　of　the　BWT　method　indicated　that　long-term　aging　decreased　the　adhesion　grade　between　SBS　modified　asphalt　and　granite　from　G4　to　G2.　NLCACRs　could　restore　the　adhesion　grade　of　ASBS-MA　and　granite　to　the　level　of　original　SBS　modified　asphalt.　The　comprehensive　analysis　of　the　influence　of　NLCACRs　on　the　interfacial　adhesion　between　ASBS-MA　and　aggregate　showed　that　the　theoretical　law　(SFE　method)　was　consistent　with　that　of　the　actual　(BWT　method).　This　study　could　help　to　explore　the　influence　of　NLCACRs　on　the　moisture　stability　of　aged　SBS　modified　asphalt　mixture　and　provide　the　theoretical　basis　for　its　application　in　practical　engineering.
