Recommendations for the application of geosynthetics in a railway network modernisation project in Slovakia

The paper deals with the use of geosynthetics in the railway network modernization project. A new track subbase arrangement with stiff integral biaxial geogrids on a low bearing capacity soft subgrade is presented. The experimental tests have been carried out with the aim of investigating the effects of geogrid within reinforced subbase. In situ plate load bearing capacity control tests confirm the track substructure improvement using geosynthetic reinforcement. For the covering abstract see ITRD E125786.
