Abstract

During the past twenty-five years, biaxial geo-grids have been used as reinforcement in the construction of railroad beds and ballasts to improve their performance and structural integrity. In the present study geosynthetic reinforced railway track were modeled using the software PLAXIS 8.2 with high geogrid stiffness at various placement depths and compared with unreinforced section. The result shows that reinforced railway track can be used to improve the performance of track with reduction in the stress and deformation of subgrade.
