This　paper　presents　a　laboratory　investigation　of　the　thermal,　electrical,　rheological　and　mechanical　properties　and　performance　of　control　and　graphite　(flake　graphite　and　exfoliated　graphite　nanoplatelet　(xGNP))　modified　asphalt　binder　and　mixture.　For　the　graphite　modified　asphalt　binder,　the　rolling　thin　film　oven　(RTFO)　test　and　pressure　aging　vessel　(PAV)　test　were　utilized　to　simulate　the　short-term　and　long-term　aging　process　of　control　and　graphite　modified　asphalt　binder,　respectively.　The　bending　beam　rheometer　(BBR)　test　and　dynamic　shear　rheometer　(DSR)　test　were　conducted　to　evaluate　the　rheological　properties　of　the　control　and　graphite　modified　asphalt　binder　at　low　and　high　temperatures,　respectively.　The　Fourier　transform　infrared　spectroscopy　(FTIR)　was　used　to　evaluate　the　oxidation　group　content　in　these　asphalt　binders.　The　thermal　conductivity　of　the　graphite　modified　asphalt　binder　increased　with　graphite　content.　For　the　graphite　modified　asphalt　mixtures,　both　thermal　and　electrical　conductivities　also　increased　with　added　graphite　modifiers.　The　measured　dynamic　modulus　results　of　mixture　performance　tests　indicated　that　the　added　graphite　particles　were　capable　of　increasing　their　moduli　at　both　high　and　low　temperatures.　The　Hamburg　wheel　tracking　device　(HWTD)　test　results　also　showed　an　improved　rutting　resistance.　As　a　result,　the　graphite　modified　asphalt　mixture　can　improve　multiple　physical　properties　and　high-temperature　performance　as　promising　conductive　materials　for　many　applications.　(C)　2017　Elsevier　Ltd.　All　rights　reserved.
