The research on color asphalt pavement can be traced back to the 1950s. It not only plays a role in dredging traffic and beautifying the city, but also reflects the local style and urban taste and improves the overall image of the city.

The black color of traditional asphalt pavement is mainly due to the influence of asphaltene in asphalt. In order to eliminate the color influence of asphaltene, light color cementitious material can be prepared by using light color polymer aromatic oil, resin filling oil and other additives. Its service performance is similar to that of ordinary asphalt and even better than that of ordinary asphalt, and then add pigment for color preparation, To form the diversity of pavement colors. Compared with spraying pigment directly on the road surface, this method can effectively improve the color retention and pavement durability, so it has been widely used.
