Abstract: Since the reform and opening up, my country's economy has taken off rapidly, and highway construction has also been greatly developed. However, in the large number of highway projects put into use, it is also facing more and more new problems, such as the early construction of cement The problems of concrete pavement diseases have followed one after another. Many road pavements are in a state of maintenance. If the driving comfort of the old cement concrete pavement cannot be improved, driving safety will be seriously affected. For this reason, the maintenance measures for adding asphalt pavement are proposed. Based on this,it is of great significance to carry out research on the construction technology of white and black pavement maintenance.
