With the increasing demand for road traffic, many old roads have been unable to meet the traffic demand. The reconstruction and expansion of the original roads have great significance for improving the capacity of roads and improving traffic conditions. In the design of expansion roads, the design of road routes, pavements and embankments has a direct impact on the quality of the expansion project. Taking Huian Avenue project as an example, this paper carefully analyzes the design scheme of subgrade expansion.
