Research Application On Pit Trough Repairing Material Of Network Engineering Cement Concrete Pavement In Heilongjiang Province

With the increment of building mileage of cement concrete pavement year by year in Heilongjiang Province, the task of protection and maintenance is move and move important, Heilongjiang Province is located at frigid area in winter, concrete pavement is easily suffered by frozen calamity, as well as move and move loaded vehicle, cement concrete pavement is heavily damaged, so it has higher demands for maintenance material performance, the performance of internal and traditional maintenance material can't suit the needs of maintenance material in the bitter environment, however, the existing external new-type maintenance material is higher inprice, can't be applied in-an-all-round way. Through research by repairing position boundary reinforcing agent of cement concrete pavement, research high-performance cement concrete repairing agent and boundary reinforcing agent and pavement repairing concrete construction method , we have developed a new-type high-performance cement concrete repair material. The repair material is close to the used concrete material in color, its technical performance is in conformity to demands of repair material, it is simple in technology and reasonable in price, it can remarkably inprove use result of cement concrete pavement after repairing, raise durability of pavement repairing, in the meantime, it provides a kind of new protection material and technology for surface damage and renovation of cement concrete pavement in Heilongjiang Province, so it has a certain of significance for large area of popularization and application.
