Abstract：Inordertoinvestigatetheinfluenceofcoal ganguepowder filermodificationon theroadperformanceof rubber asphalt mixture，coal gangue powderandlimestone powder wereused to analyze theroad performance ofrubber asphalt mixture ARHM-13（W).The microscopic propertiesof the filers were compared by SEMand XRF tests，thephysical and mechanicalindexesof thefilerswerecomparedbyMarshalltestundertheoptimaloil stoneratio，andtheperformancendexes werecompared byhigh temperatureruting test，lowtemperature trabecular bending testand freeze-thawsplitingtest.The results showthatthesurface structureofcoal gangue powder ismorecomplexthanthatoflimestonepowder，containingflake structure，larger specific surface area，containing more active oxides such as and ，which can be used as a good filler.Teoptimumratioofoil stone，dynamicstability，permanentdeformation，spliting strengthratio，hightemperature performanceandwaterstabilityofcoal ganguepowderfllng rubberasphalt mixtureare improved.Thebending stiffess modulus oflimestone powderfilerrubberasphalt mixtureis lower，thelimit bending tensionshouldbechanged greatly，and the low temperature performance isrelativelygood.Whenthedynamic stability，deformation，strength，hightemperatureperformance and waterstabilityofrubberasphalt mixture arerequired，coal gangue powdercanbeusedasfiler，whichcanimprove theroad performance of asphalt mixture and improve the utilization rate of coal gangue.
