Abstract

The invention discloses colored asphalt and a production method thereof and belongs to the technical field of road engineering materials. The invention discloses the colored asphalt and a production method thereof. The colored asphalt comprises petroleum resin, base oil, a coupling agent, epoxy resin, rubber powder, an SBS modifier, an inorganic filler and the like. The colored asphalt with various colors can be produced, the vision is improved, the colored asphalt can be widely applied to different places such as streets, sidewalks and landscape roads, the requirements of various places can be met, and meanwhile, the environment can be beautified. According to the present invention, the variety of used additives for the production of the water-permeable colored asphalt is less, and the high-speed shearing and additional equipment are not required when the SBS modifier is added, the production cost and the production procedure are reduced, and the production process is generally simplified. According to the production method, a special asphalt production device is used for production, the production efficiency is high, the technological process is simple, the cost is low, and the large-scale production is easy.

Description

technical field [0001] The invention relates to the technical field of road engineering materials, in particular to a colored asphalt and a production method thereof. Background technique [0002] Colored asphalt pavement not only has the good properties of ordinary asphalt concrete, such as strong elasticity, strong vibration damping and easy cleaning and washing, but also improves the black monotony of ordinary asphalt pavement, and can be matched and coordinated with the surrounding buildings and landscapes. landscape benefits. In addition, the role of colored asphalt in traffic organization and management has been paid more and more attention. Different colors of asphalt pavement can improve the recognition effect of the driver, and can also make the driver's attention more concentrated, thereby playing the role of inducing traffic flow, driving safely, and making traffic management intuitive. For example, in urban road traffic accident-prone areas, red or yellow pavem...
