Utilização de reforço geossintético em vias ferroviárias

This report analyses the use of geosynthetics in railways for subgrade reinforcement and separation of the track layers. Cases of instrumented test sections were studied. These test sections were located in Australia (with geocomposite applications), Brazil (with geotextile and geodrid applications) and China (with geotextile and geodrid applications). Railway design methods using geosynthetics applications were analyzed as well. Based on a studied case for implementation of geosynthetics in a German railway, a railway track was simulated with and without the use of geosynthetics, respectively on PLAXIS v.8 and FERROVIA 3.0 softwares. The performance benefits of the geosynthetics applications in railways were, therefore, confirmed, based on the simulation results
