Product Detail
1、 Product Introduction
Colored asphalt: Using modifiers, high molecular polymers, petroleum resins, and other materials, a light colored binder with comparable performance to asphalt is prepared by shearing and stirring in a certain proportion. Special pigments of a certain color are added to make the asphalt turn into different colors such as red, yellow, blue, green, etc. as needed. At the same time, it has higher adhesion, elasticity, and toughness than ordinary asphalt.
2、 Characteristics of the product
Our company's high-performance colored asphalt binder pavement has good durability, rich and vibrant colors that do not fade, high and low temperature stability, strong resistance to rutting, safety and water seepage, environmental protection and pollution-free, fast construction and open traffic, low cost, and is used in motor vehicle lanes, and so on.
