The deep on-site cold regeneration for the old asphalt pavement level of the increase, the old asphalt layer and grass at the same time milling broken, and then add other materials, flattened as a new layer of grass-roots level, and then paved on the grass The new surface, which is a road to transform the economic and effective way of construction, so the full-deep local cold regeneration method is being accepted by more and more projects. This recycled road is mainly used for low-grade road pavement and high-grade road pavement (China's asphalt network) grassroots (but will improve the road elevation), does not apply to the surface of the high-level pavement. Since the implementation of the reform and opening up policy, China's rapid development of highway construction, by the end of 2010, China's total mileage has reached 400.8 million km highway, highway mileage of 74,000 km. With the development of the national economy, the traffic volume of motor transport increased significantly, and the carrying capacity of the road was more and more heavy, which accelerated the wear of the highway. The task of highway maintenance is getting heavier. Most of the early construction of the highway has entered the renovation period, therefore, asphalt pavement regeneration equipment in China has a very good development prospects. ultra thin friction course equipment management system development used milling machine accessories head resurfacing machine for sale
