Abstract: In recent years, my country's social and economic development has been very rapid, and the process of urbanization has been gradually accelerated. Under this background, the number and scale of road projects are increasing day by day. The quality of roads has a direct impact on social and economic development and people's daily production and life. In order to ensure the quality of roads, it is necessary to pay enough attention to the testing and testing of road materials and roadbeds. This paper conducts in-depth research and analysis on road raw materials and road subgrade test detection, and on this basis puts forward corresponding detection strategies for reference.
