Abstract: With the large-scale road construction, road facilities in the soft soil foundation has gradually be-come the main cause of highway engineering quality. The main purpose of soft soil sub-grade treatment is to improve the engineering properties of soft soil sub-grade, so that it can meet the requirements of the relevant specifications for the stability and deformation of the foundation. In this paper, the application of soft soil sub-grade processing technology are introduced in detail, and discusses the technological innovation and the application of road engineering construction process, the soft soil sub-grade treatment.
