What’s more, the colored asphalt road surface is with high temperature stability, great resistance to water damage of asphalt pavement and durability, and less deformation phenomenon and peelings of bitumen membrane. And the bright color is long lasting, non-deformation, quite beautiful. And the high temperature resistance if of -23 to 77℃, convenient to maintain. At the same time it has good elasticity and flexibility, and can also prevent slippery in the winter, suitable for people having a walk.
