Rail

Railway construction can involve many challenges -- from track support over weak subgrade conditions to bridge abutments and sediment control. As experts in mechanically stabilized earth (MSE) solutions, Tensar International developed the Spectra® Rail Railway Improvement System to increase the service life of rail track substructures. Tensar® Geogrids, in combination with aggregate, are used to stabilize sub-ballast and ballast layers, decreasing required roadbed thickness while improving track performance. A cost-effective alternative to conventional solutions, the Spectra Rail System has proved to save significantly on installation and life cycle costs as well.

Tensar® Geogrids, in combination with aggregate, are used to stabilize sub-ballast and ballast layers, decreasing required roadbed thickness while improving track performance.

In addition to the Spectra Rail System, Tensar offers other applications used in railway site development projects. These applications include:

  • Intermodal roadway sections and loading surfaces
  • Construction access road support
  • Bridge approaches
  • Retaining wall structures
  • Steepened slopes and slope repair structures
  • Erosion control applications
  • Geopier® Foundation Systems
