The structural support of a rail line is an essential component of successful railroad construction and maintenance. It can involve a number of challenges including the mitigation of soft or variable soil conditions, ballast restoration and track realignment.
The use of geogrids is an innovative alternative for addressing a wide range of soil and loading conditions and is included in guidance for trackbed design by the American Railway Engineering and Maintenance-of-Way Association (AREMA). Developed to mechanically stabilize sub-ballast and ballast layers, Tensar International’s Spectra®Rail Railway Improvement System is a proven solution based on Tensar® Geogrid technology.
