Abstract

The invention discloses anti-ultraviolet asphalt as well as a preparation method and application thereof. The anti-ultraviolet asphalt is mainly prepared from the following components in parts by weight: 75-85 parts of asphalt, 3-5 parts of a modifier, 3-5 parts of a light screener with a sandwich structure, 3-5 parts of an auxiliary light screener, 1-3 parts of an antioxidant, 1-3 parts of an anti-aging agent, 1.5-1.7 parts of an ultraviolet light absorber, 1-3 parts of a free radical scavenger and 0.3-0.5 part of a light stabilizer. The modified material added in the anti-ultraviolet asphalt has good compatibility with asphalt and is uniformly dispersed to form a continuous-phase protective layer, ultraviolet rays can be reflected and scattered through the double-layer inorganic light covering layer, the damage of the ultraviolet rays to a pavement is reduced, and the asphalt has small infrared ray absorption and can partially convert the absorbed ultraviolet rays into heat energy, so that the pavement has an energy storage function, the anti-ultraviolet capability of the asphalt pavement is greatly improved, and the service life of the pavement is prolonged.

Description

technical field [0001] The invention relates to the technical field of road asphalt, in particular to an anti-ultraviolet asphalt and its preparation method and application. Background technique [0002] The aging of asphalt is generally divided into thermal aging caused by high temperature and ultraviolet aging caused by ultraviolet radiation contained in sunlight. Photo-oxidative aging is the main cause of long-term aging of asphalt pavements. The energy of ultraviolet rays exceeds C-C, and the bond energy of C-H bond breaks, the weaker chemical bonds inside the asphalt molecules break, and a chemical reaction occurs, which leads to changes in the molecular structure, resulting in a decrease in performance. A large number of condensed ring compounds in asphalt, SBS modifier and other strong ultraviolet absorption ability, photolysis reaction occurs, leading to aging, affecting performance and road life. Asphalt mixture is a black material, and the anti-ultraviolet absorb...
