Abstract

The invention discloses a reflective coating layer material for a tunnel pavement and a preparation method of the reflective coating layer material, and belongs to the field of road engineering. The coating layer material is prepared from a main solvent I, an asphalt cementing material, a functional filler, a modified master batch, a stabilizer and a drier according to a specific ratio, is sprayed on the surface of a tunnel pavement, can increase the retroreflection coefficient of the pavement to 10 mcd.(1x.M<2>)<-1> or above, and can greatly increase the brightness and uniformity of the pavement compared with a conventional pavement, so that the illumination in the tunnel is improved, the illumination energy consumption is saved, the driving safety of the tunnel is improved, the implementation process is simple and convenient, the performance is stable, and good popularization and application values are achieved.

Description

technical field [0001] The invention relates to the field of road engineering, and specifically provides a reflective coating material for tunnel pavement and a preparation method thereof. Background technique [0002] In order to protect the natural environment, the application ratio of tunnel engineering in high-grade highways is very high. As the mileage of tunnels in my country increases year by year, in order to ensure traffic safety, the energy consumption of lighting in tunnels is also increasing. This runs counter to the policy of green lighting and energy conservation actively advocated by the country. Illumination, to solve the problem of energy consumption caused by lighting, has become an urgent industry problem. [0003] The requirement for high reflective properties of the tunnel pavement is put forward from the aspect of lighting. The International Commission on Illumination (CIE) proposed a total of 5 grades of lighting-based pavement classification from R1 ...
