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.
In applications ranging from light rail to heavy Class 1 rail structures, the Spectra Rail System reduces trackbed thickness and/or lengthens service life with no loss of performance. It helps rail installations resist track settlement and general wear and tear, reducing maintenance costs in the short and long term.
The safety and performance of any rail track are directly affected by the sub-ballast and ballast layers, which together form the track bed structure. The Spectra Rail System can be used to stabilize both layers to maximize design efficiencies and performance, and to minimize service disruptions.
