Expansive soil roadbed is a kind of disease problem in our country highway project with extremely wide harm, our country highway project in the process of operation, often due to the existence of expansive soil in the roadbed structure and cost extension, construction cycle extension, etc. At the same time, improper handling of the expansive soil will also be followed by the vehicle traffic will bring great safety hazards. Therefore, how to do a good job for highway roadbed expansion soil soil improvement has become a key entry point to ensure the safe operation of highway projects. This article mainly analyzes the improvement method of expansive soil, and the construction technology of highway roadbed expansive soil improvement is explored, hoping to ensure the safe operation of the highway to provide reference.
