Research on Construction Technology of Micro-surface in Pavement Maintenance Engineering

Due to the influence of traffic load and natural factors,after a certain period of time when asphalt concrete has been opened to traffic,different degrees of diseases will often appear,such as cracks,ruts,and shifting.The appearance of diseases will greatly affect the traffic quality of highways.Therefore,it is necessary to carry out maintenance and repair in time,so as to suppress the development of diseases and restore the performance of the road surface.Micro-surfacing is one of the key technologies for pavement preventive maintenance.Reasonable application of micro-surfacing technology can effectively repair road defects and prolong the service life of the project.
