Asphalt　undergoes　thermal-oxidative　and　ultraviolet　(UV)　aging　in　its　lifespan,　yet　current　research　tends　to　emphasize　the　enhancement　of　asphalt＇s　resistance　to　only　one　type　of　aging,　which　hinders　the　improvement　of　its　overall　durability.　In　order　to　improve　the　resistance　of　asphalt　to　thermal-oxidative　and　ultraviolet　aging,　LDHs　and　antioxidants　were　utilized　to　modify　asphalt　based　on　the　concept　of　physical　shielding　and　chemical　blocking.　Moreover,　to　boost　the　compatibility　between　LDHs　and　asphalt,　LDHs　were　organically　modified　using　salicylic　acid　(SA)　and　sodium　sodium　dodecyl　benzene　sulfonate　(SDBS).　The　composite　effect　of　organic　LDHs　and　antioxidants　(Irganox　1076　and　Irganox　1010)　was　investigated　through　physical　and　rheological　tests.　Also,　thermal-oxidative　and　UV　aging　tests　were　utilized　to　evaluate　the　effectiveness　of　organic　LDHs　and　antioxidants.　Results　show　that　SDBS　and　SA　can　be　effectively　intercalated　into　the　LDHs,　which　improves　the　compatibility　between　LDHs　and　asphalt.　LDHs,　as　a　rigid　component,　increases　the　shear　resistance　of　asphalt,　which　contributes　to　improved　high-temperature　performance　but　diminishes　its　flexibility.　Organic　modification　can　mitigate　this　drawback.　In　contrast,　antioxidants　exhibit　a　softening　effect　on　asphalt.　Organic　LDHs　and　antioxidants　can　simultaneously　boost　the　resistance　of　asphalt　to　UV　and　thermal-oxidative　aging,　with　no　interference　observed　between　the　two.　Besides,　the　composite　effect　between　SDBS-LDHs　and　Irganox　1076　is　limited,　whereas　the　composite　effect　of　SA-LDHs　and　Irganox　1010　shows　the　most　notable　improvement.　This　can　be　attributed　to　the　composite　mechanism　in　which　SA-LDHs　provides　physical　shielding　and　Irganox　1010　chemically　blocks　the　chain　aging　process　of　asphalt.　These　findings　provide　novel　insights　into　the　improvement　of　asphalt　and　asphalt　pavement　durability　through　a　combined　physical　and　chemical　strategy.
