Problems solved by technology

[0002] At present, my country has a mature decolorization technology, which can produce light and highly transparent asphalt, but it also has new problems. Under the reflection of sunlight, it is easy to cause glare, visual fatigue and other shortcomings, which makes the vision of vehicle drivers very easy. Fatigue is not conducive to driving safety
[0003] In addition, asphalt is the most widely used high-grade pavement in road construction. Under the long-term action of asphalt in the natural environment and vehicle load, various irregular-shaped cracks will gradually appear, which seriously affects the appearance and use of the pavement. In the subsequent repair process In the process, it needs to spend a lot of money, time and effort. If it is not repaired in time, the overall strength of the road surface will decrease in the long run, resulting in subsidence of the roadbed.

Abstract

The invention discloses environment-friendly high-transparency asphalt and a preparation method thereof, and relates to the technical field of asphalt. The decolored asphalt, the fluorescent fibers and the auxiliaries are subjected to first-time foaming treatment, then silicon rubber is sprayed, second-time foaming treatment is carried out, supercritical carbon dioxide is assisted by electron beam irradiation, a three-dimensional cross-linked network-shaped multi-layer foam structure is formed with foamed asphalt, and the buffering and compression resisting effects of the asphalt are improved; the preparation method comprises the following steps: preparing hollow polystyrene microspheres / polyester fibers with a bead string structure by utilizing electrostatic spinning, then carrying out soaking treatment twice and assisted by a nanosecond pulse electric field to form silver nanosheets, then spin-coating the surfaces of the silver nanosheets with a polymethyl methacrylate solution, carrying out low-pressure tube sealing treatment to form graphene, and finally, carrying out ozonization etching by utilizing ultraviolet light, so as to obtain the graphene. The fluorescent fiber is obtained, so that the asphalt has photochromic capability. The environment-friendly high-transparency asphalt prepared by the invention has the effects of buffering, pressure resistance and visual comfort.
