Layered　double　hydroxides　(LDHs)　have　been　alternatively　employed　to　improve　the　ultraviolet　(UV)　aging　resistance　of　bitumen　due　to　their　high　UV　reflectance,　but　LDHs　particles　cannot　be　dispersed　into　bitumen　uniformly　and　stably　since　their　poor　compatibility　with　bitumen.　Therefore,　the　problem　of　poor　compatibility　must　be　solved　before　its　application.　Generally,　organic　modification　can　change　the　surface　characteristics　of　inorganic　particle　and　then　improve　the　compatibility.　The　objectives　of　this　work　are　to　evaluate　the　effect　of　prepared　various　organic　LDHs　on　the　anti-UV　aging　property　of　bitumen　and　then　determine　an　optimal　organic　LDHs　for　bitumen　modification.　For　these　purposes,　three　organic　anions,　sodium　dodecyl　benzenesulfonate　(SDBS),　sodium　dodecyl　sulfate　(SDS)　and　sodium　dodecyl　sulfonate　(SDSO),　were　used　as　organic　modifiers　to　prepare　organic　LDHs　(OCLDHs),　then　the　storage　stability　and　anti-UV　aging　of　OCLDHs　modified　bitumen　were　investigated.　Experimental　results　show　the　organic　modification　can　suppress　the　separation　phenomenon　of　OCLDHs　modified　bitumen　during　the　high　temperature　storage,　indicating　the　compatibility　and　stability　of　the　mixture　is　ameliorated.　Compared　with　LDHs　modified　bitumen,　OCLDHs　modified　bitumens　show　lower　aging　degree　during　UV　exposure,　which　indicates　that　OCLDHs　exhibit　better　effect　in　enhancing　the　anti-UV　aging　performance　of　bitumen.　FTIR　analysis　indicates　that　OCLDHs　effectively　retard　the　formations　of　oxygen-containing　functional　groups　and　aromatic　structure　of　bitumen.　Furthermore,　SDBS　is　a　preferable　modifier　for　the　preparation　of　organic　LDHs　due　to　the　most　effective　improvement　in　compatibility　with　bitumen　and　UV　aging　resistance　of　bitumen　as　compared　with　SDS　and　SDSO.　©　2018　Elsevier　Ltd
