In　this　study,　compound　regeneration　of　SBS-modified　bitumen　(SMB)　was　carried　out　by　a　composite　rejuvenator　composed　of　furfural　extraction　oil　(FEO)　and　1,6-hexanediol　diglycidyl　ether　(HDDGE)　in　the　presence　of　catalyst　triethanolamine　(TEOA).　SMB　was　subjected　to　three　aging-regeneration　cycles,　and　the　physical　and　rheological　properties,　toughness　and　tenacity,　and　chemical　structures　of　the　SMB　after　each　aging-regeneration　cycle　were　tested　to　investigate　the　regeneration　effect　of　the　composite　rejuvenator　on　SMB　at　different　numbers　of　cycles.　The　ductility　decreases　and　low-temperature　properties　deteriorate　as　the　number　of　cycles　increased,　but　the　high-temperature　properties　of　the　SMB　are　improved.　The　complex　modulus　aging　index　and　phase　angle　aging　index　indicate　that　the　viscous　behavior　of　SMB　weakens　after　the　second　and　third　aging.　The　degree　of　viscoelasticity　and　toughness　recovery　decreases　with　the　increase　in　the　number　of　cycles,　and　the　tenacity　of　SMB　after　the　third　aging-regeneration　cycle　is　basically　lost.　The　results　of　the　Fourier　transform　infrared　(FTIR)　spectra　tests　prove　that　with　the　increase　in　the　aging-regeneration　cycles　of　SMB,　the　intensity　of　FTIR　peaks　of　oxygen-containing　functional　groups　is　greater,　and　the　recovery　of　aged　SMB　is　gradually　weakened.
