Abstract: In the process of urban construction, the road first is a very important principle. In recent years, with the rapid development of China's social economy, the urbanization process is also accelerating, and the number of highway projects has been increasing, which has brought great convenience to the normal travel of people's life. Therefore, at the present stage, in the process of the highway project construction work, we should also further strengthen the management and supervision work. Strengthen the quality and monitoring of the highway subgrade and road surface construction, to achieve the best ideal construction effect.
