Abstract

The invention provides a colored asphalt cement which is characterized by comprising the following components in parts by weight: 100 parts of petroleum resin, 80-120 parts of extract oil, 5-10 parts of polyethylene wax, 20-30 parts of light-accumulative luminescent material and 20-30 parts of reflecting material. Since the luminescent material and the reflecting material are simultaneously added into the colored asphalt cement, the colored asphalt pavement formed by the colored asphalt cement is colorful at daytime and can achieve a favorable vision promotion effect at night, thereby enhancing the recognition capabilities of drivers and improving the traffic capacity and traffic safety of roads. Besides, the invention can reduce the radiant heat of the roads, decrease the heat island effect of the city and effectively save the energy.

Description

technical field [0001] The invention relates to a novel colored asphalt binder and a preparation method thereof, in particular to a colored asphalt binder with the function of preventing solar radiation and a preparation method thereof, belonging to the field of building materials. Background technique [0002] The identifiability of urban roads will have an important impact on people's behavior, and identifiability is an important content of urban road traffic safety. Colored asphalt pavement can divide different types of traffic sections through color changes, which is very beneficial to traffic safety. At present, colored pavement has been widely used in highways, bicycle lanes, sidewalks, bus lanes, pedestrian areas, squares and home driveways, and has played a good role in beautifying the urban environment and organizing traffic. [0003] At present, most of the used colored asphalt is mixed with decolorized asphalt and inorganic dyes. For example, patent 01138806.4 di...
