Abstract：Inorder to studytheviscoelastic propertiesof high-viscosityasphalt mortar onopen-gradedanti-skidabrasion layer（OGFC）modified pavement，a modified asphalt mortar for OGFC modified pavement was prepared by using thermoplastic elastomer（SBS）and tri-embedded copolymer material（SEBS）combined with basalt ore，and the modifier was mixed with matrixasphalt to prepare high-viscosityasphalt mortarfor OGFC modified pavement.The testresults showed thatwhen thepowder-glueratiowas1.，theviscosityof theasphalt was the mostsuitable，theelasticrecoveryrateof the asphalt was superiorafter modification，the bending creepratevalueof theasphalt was highin the low temperature environment，andtheasphalt strainvaluewas high inthehigh temperatureenvironmentand high stre environment，andcan be applied to the OGFC pavement in the high temperature environment and high stress environment.
