Anti-aging asphalt, and preparation method and use thereof
An anti-aging asphalt, and preparation thereof. The anti-aging asphalt includes, in parts by weight: 100 parts of asphalt, 0.5 parts to 1 part of a primary antioxidant, 1 part to 5 parts of an anti-ultraviolet radiation aging agent, 0.05 parts to 0.1 parts of a hydroperoxide decomposer, and 0.3 parts to 1 part of a free radical scavenger. The primary antioxidant may be a hindered phenol, a hindered amine, and an aromatic secondary amine; the anti-ultraviolet radiation aging agent may comprise an organic ultraviolet absorber and an inorganic light-shielding agent; the hydroperoxide decomposer may be a phosphite; and the freed radical scavenger is a hindered amine. The method of forming the asphalt comprise: heating the original asphalt to a molten state, adding the anti-ultraviolet radiation aging agent, and stirring; adding the primary antioxidant, hydroperoxide decomposer, and freed radical scavenger, and stirring; then stirring again to obtain the anti-aging asphalt.
