Abstract

The invention discloses an anti-ultraviolet-aging high-viscosity asphalt additive and a preparation method thereof, wherein the high-viscosity asphalt additive comprises the following raw material components by weight: 100 parts of SBS, 20-40 parts of a petroleum resin, 10-40 parts of aromatic hydrocarbon oil, and 5-10 parts of an organic-inorganic composite material, wherein the organic-inorganiccomposite material is formed by carrying out a co-hydrolysis and condensation polymerization reaction on tetraethyl orthosilicate and organosilane containing a triazinetrione group. According to thepresent invention, with the additive, the viscosity and the adhesion of the asphalt can be significantly improved, the compatibility with the asphalt is good, and the ultraviolet aging resistance of the asphalt can be substantially improved.

Description

technical field [0001] The invention relates to a high-viscosity asphalt additive and a preparation method thereof, in particular to a high-viscosity asphalt additive with anti-ultraviolet aging performance and a preparation method thereof. Background technique [0002] High-viscosity asphalt generally refers to asphalt with a dynamic viscosity greater than 20,000 Pa·s at 60°C, which is suitable for the application of open-graded anti-skid wear layer (OGFC) and other road surfaces. OGFC pavement has good drainage, noise reduction and anti-skid performance due to its large void ratio. However, the structural characteristics of large voids also lead to an increase in the contact area between asphalt and air and ultraviolet light, which accelerates the aging of asphalt and shortens the service life of the pavement. [0003] At present, high-viscosity asphalt is mainly prepared by adding polymers to asphalt, which can significantly improve the high and low temperature performan...
