With the rapid development of social economy, my country's highway construction has also developed by leaps and bounds. In subgrade reconstruction projects, the phenomenon of differential settlement between new and old subgrades often occurs. The long-term existence of such problems will further aggravate pavement diseases and cause problems such as cracking and deformation. The application of geogrid in the subgrade reconstruction project can not only realize the effective improvement of the stiffness of the new subgrade and reduce the settlement; at the same time, it can also rely on the tensile strength of the geosynthetic material to further strengthen the structural connection between the widened part and the original subgrade. Form a whole, effectively improve the performance of the project, and promote the sustainable and healthy development of highway construction.
