The application provides a kind of composite modified asphalt with anti-ultraviolet and anti-salt corrosion aging and a preparation method thereof, and the preparation raw materials include base asphalt, linear SBS, GN, LDHs-PABA-CA, a compatibilizer and a stabilizer.The base asphalt is heated to a molten state to obtain molten asphalt.Under the condition of constant temperature heating and continuous stirring, linear SBS is added to the molten asphalt to make linear SBS swell in the molten asphalt, and then shear mixing is carried out to obtain SBS composite modified asphalt.GN and LDHs-PABA-CA are added to the SBS composite modified asphalt and stirred uniformly, and shear mixing is continued to obtain a composite modified asphalt base with anti-ultraviolet and anti-salt corrosion aging.A compatibilizer and a stabilizer are added to the composite modified asphalt base with anti-ultraviolet and anti-salt corrosion aging, and then the mixed system is stirred under constant temperature conditions to obtain a composite modified asphalt with anti-ultraviolet and anti-salt corrosion aging.
