Abstract

The invention provides a colored asphalt mixture, which is characterized in that raw materials comprise a colored asphalt binder, a pigment and aggregates; the aggregates comprise coarse aggregates, fine aggregates and mineral powder; and the colored asphalt binder comprises the following components by weight portion: 100 portions of petroleum resin, 80-120 portions of extracted oil, 5-10 portions of polyethylene wax and 0.1-2 portions of thermoplastic acrylic resin. Since the polyethylene wax and the thermoplastic acrylic resin are simultaneously added into the colored asphalt binder, the dispersion and the durability of the pigment can be improved. Moreover, the performance of the colored asphalt binder is the same as or superior to the performance of black asphalt mixture in the looseness, compactness and initial strength, the strength of the formed mixture, water damage resistance and the like.

Description

technical field [0001] The invention relates to a colored asphalt mixture 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] In the past, most of the colored asphalt pavements used ordinary decolorized asphalt products, which had poor dispersibility of pigments, poor road performance, and serious pavement cracking; poor color durability, serious pavement fading, and the effect was no...
