Abstract：

Two　organic　layered　double　hydroxides　(LDHs)　were　synthesized　and　utilized　to　enhance　the　anti-aging　property　of　bitumen.　Fourier　infrared　spectroscopy　and　X-ray　diffraction　showed　that　sodium　dodecyl　sulfate　was　intercalated　into　the　interlayers　of　LDHs　(I-LDHs),　and　γ-(2,3-Epoxypropoxy)propyltrimethoxy　silane　was　chemically　grafted　onto　the　surface　of　LDHs　(S-LDHs).　Compared　with　LDHs,　organic　LDHs　possessed　better　compatibility　and　organic　LDHs　modified　bitumen　exhibited　better　performance　in　high-temperature　regions,　especially　S-LDHs.　After　aging,　the　rheological　properties　dramatically　deteriorated.　The　content　of　aromatic　in　bitumen　evidently　decreased,　and　the　asphaltene　noteworthy　increased,　the　colloid　structure　verged　on　the　gel　system.　The　incorporation　of　LDHs　could　relieve　the　damage　of　aging　on　the　rheological　properties　and　colloid　structure,　and　strengthen　the　anti-aging　property　of　bitumen.　Moreover,　the　consequence　of　LDHs　had　been　further　enhanced　obviously　after　organic　modification,　and　S-LDHs　exhibited　more　excellent　performance　compared　with　I-LDHs.　©　2023　Elsevier　Ltd
