On the other hand, there are much larger quantity of cracking PCCPs and asphalt pavements. The anti-reflective overlay is desired by highway administrators.
China began its research and application on rubberized asphalt pavement in early 1980s, got many test results and test sections, but do not see industrial application until 2003, due to problems of equipment, policy, specification, etc. The first comprehensive study on rubberized asphalt finished in 2003 had much accumulation. Gold Bond imported AR blender and spreader from US for the first time. Several test sections were constructed. Compounded
