Abstract: With the continuous development of the socialist market economy in our country, the national policy to constantly improve and road traffic and transportation will continue to progress, China Road and bridge engineering construction both speed and scale have made a major breakthrough. The rapid development of road and bridge engineering construction technology requirements are more and more high, the new era of new background, to strengthen the road and Bridge subgrade construction technology analysis has important practical significance. This article is conducted to provide some ideas for the further development of our country in the road and Bridge subgrade construction technology in China in the road and Bridge subgrade construction technology development status, and explore the road and Bridge subgrade construction technology strategy research.
