Increasing the stability of the track in areas of rail joints through the use of geosynthetic reinforcing materials

Abstract

The study presents a method for improving the stability of railway tracks in the areas of rail joints through
the use of reinforcing and separating layers made of geosynthetic materials. The engineering aspects of
applying geotextiles and planar geogrids are considered, along with their impact on stress redistribution,
deformation reduction, and increased subgrade modulus of elasticity. Comparative data are provided for
unreinforced and reinforced subgrades. The results confirm the effectiveness of geosynthetics in both
capital and routine track maintenance. Conclusions are drawn on the potential of this technology for highspeed
rail applications.
