Abstract: A severe form was faced with WeiNan old road reconstruction task. The in situ cold regenerated technology application in rural road for old road reconstruction was introduced combined with the project. Old road diseases treatment technology, key control points of cold regeneration and its construction technology was introduced base on the survey and research. Through more than four years continuous survey, the performance of implementation project was good, which showed that in situ cold regenerated technology in rural highway has applicability for the old road reconstruction, its economic and social benefit is remarkable.
