Problems solved by technology

[0004] However, ordinary colored asphalt binders cannot be directly used to prepare colored permeable asphalt mixtures for motor vehicles. On the one hand, because the porosity of permeable asphalt mixtures reaches 20%, there are fewer bonding points between aggregates, so high-viscosity asphalt mixtures must be used. Modified asphalt can obtain higher pavement strength and maintain a higher porosity, while ordinary SBS modified asphalt has a lower viscosity, and the asphalt film on the surface of the aggregate particles is thinner, and the aggregate particles are easy to fall off, causing the road surface to be loose and not durable. Aging, poor resistance to water damage
In addition, it is a good choice to prepare modified asphalt from rosin resin, an excellent natural tackifier, but rosin contains reactive double bonds and carboxyl groups, is unstable to light, heat, and oxygen, and exhibits poor aging resistance. Poor weather resistance, easy chalking and discoloration, need to overcome this defect in use

Abstract

The invention discloses a high-performance colored cementing material and a preparation method thereof, and belongs to the technical field of colored asphalt. The colorized cementing material with high viscosity, water erosion resistance, aging resistance and high photo-thermal stability is obtained by mixing and compounding the rosin resin, the self-crosslinking resin, the anti-ultraviolet nanoparticles and the modified asphalt and controlling the ratio of the rosin resin, the self-crosslinking resin and the anti-ultraviolet nanoparticles. The cementing material obtained by the invention is used for paving a colored pavement; the invention can obtain a colored asphalt permeable pavement with excellent performance and common advantages of a permeable pavement and a colored asphalt pavement, and has a very good application prospect.

Description

technical field [0001] The invention belongs to the technical field of colored asphalt, and in particular relates to a high-performance colored binder and a preparation method thereof. Background technique [0002] The rapid economic development and the acceleration of urbanization have led to more and more hardened urban roads. Among them, colored asphalt is used to pave roads such as parks, bicycle lanes, bus lanes, and urban landscape roads. On the one hand, unlike ordinary asphalt pavement, colored asphalt pavement uses colored asphalt binder prepared from resin materials, base oil, high molecular polymer, etc., which has low cost, stable color, ductility, and high temperature stability. Better performance, low temperature crack resistance and durability; on the other hand, colored asphalt pavement has the advantages of coordinating with the surrounding environment, beautifying the city, reducing driving fatigue, and promoting driving safety. [0003] In order to build ...
