Problems solved by technology

However, these patents need to be heated to extremely high temperatures during specific construction, which not only requires a lot of energy consumption, but also pollutes the environment, makes construction difficult, and it is impossible to add too many polymers to the composition, which limits the color. The high temperature stability of asphalt binder is not conducive to popularization and use

Abstract

The invention provides a novel color asphalt mixture, which is composed of color asphalt cementing agent, pigment, and aggregates. The aggregates comprise coarse aggregates and fine aggregates. The color powder is organic. The color asphalt cementing agent comprises 100 parts of petroleum resin, 80 to 120 parts of extract oil, 5 to 10 parts of polyethylene wax, and 0.1 to 2 parts of thermoplastic acrylic resin. By simultaneously adding polyethylene wax and thermoplastic acrylic resin into the color asphalt cementing agent, the dispersity and durability of pigment can be improved; and moreover the properties of provided color asphalt mixture can reach or even exceed the properties of black asphalt mixture, such as loose property, compactability, primary strength, strength after moulding, water damage resistant performance, and the like.

Description

technical field [0001] The invention relates to a novel 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 ...
