Color function road surface

Abstract

The color functional road surface features that it is porous polymer concrete layer comprising white cement 200-500 weight portions, stone material 500-2000 weight portions, vinyl acetate copolymer 10-200 weight portions, inorganic pigment 0.5-20 weight portions, dibutyl phthalate 0.5-90 weight portions, aluminum silicate or fine silica powder 10-100 weight portions, antiageing fiber 0.5-10 weight portions and water 70-200 weight portions. The color functional road surface has good water permeability and is color fast.

Description

Technical field:

[0001] The invention relates to roads and surface layers of roads. technical background:

[0002] The structure of highways and roads generally consists of a surface layer, a base layer, and a subgrade. The surface layer located at the upper end of the highway and road is called pavement. The change of pavement structure and components brings some functions to the pavement, such as permeable pavement, colored pavement, environmental protection pavement, etc. Chinese patent 02116226, 3 just discloses a kind of colored pavement, and the pavement is made up of two layers: load-bearing layer and the colored spray coating that is positioned at the upper end of load-bearing layer, and spray coating is made up of main agent and hardening agent, and main agent comprises epoxy resin etc. , the cost is high; in addition, the sprayed layer is sprayed on the load-bearing layer, which affects the water permeability of the load-bearing layer; in addition, the function of...
