Most of the road early construction in China has entered the large , repair , every year a large number of asphalt pavement in need of repair , renovation , re- paving a new road structure on the basis of the old road , not only to raise the road , the original road facilities no longer applicable , the high cost of maintenance , and waste of resources. Renewable technology, making the old road materials can be re-used , and can restore road performance , sustainable development strategy , but also need the engineering and technical personnel need to explore further . Papers on the basis of existing research results at home and abroad , using the full depth situ cold recycling technology ( FDR ) semi - rigid base asphalt pavement , explore the the FDR technical mechanism and reliable structural design methods , analysis of FDR Mixture Performance , combined with State Road 108 West Baonan line the Huxian segment maintenance engineering , in-depth analysis and research on the FDR construction technology and quality control . The results show that the full depth in situ cold recycling (FDR) road base technology theoretically feasible , workable , the economy is good . The paper provides a set of FDR construction quality control methods, cold recycling technology implementation of the project after road base provides a theoretical basis and practical experience .
