Abstract：Theanti-ultravioletaging performance of high-viscosityandhigh-elasticity modifiedasphalt pavement structure was analyzed，and the guidance for pavement upgrading was provided.Nano - ，nano - and layered dihydroxides （LDHs）were used as anti-ultraviolet modifiers to prepare testsamples of high-viscosity and highelasticity modified asphalt pavement structure.Each sample was placed in aself-made ultravioletaccelerated irradiation testchamber forultraviolet aging test，and the basic indexes，mechanical propertiesandruting test effects were compared.The experimental analysis showed that the basic indexes of the pavement structure using LDHs anti-ultraviolet light modifier were the best，and the tensile strength and ruting stability were high.Under the dosage of 7.5 LDHs anti-ultraviolet modifier，the stability of pavement structure was the best，and the spliting strength was the highest after ultraviolet aging.
