On-Demand Webinar: Mechanical Stabilization for Improved Trackbed Performance
Written by Erica Hayes
The construction and maintenance of track inventory is a major component of operating costs for all railroads. In addition to the direct construction and maintenance costs, the condition of trackbed structures affects other aspects of operations, including allowable operating speeds and safety. The mechanical stabilization of ballast and sub-ballast using geogrid can offer significant improvements in trackbed performance, by providing a stiffer, longer-lasting structure with reduced deflection under load. View this on-demand webinar now to learn about design methodology and supporting information for the successful use of triaxial geogrid for mechanical stabilization in trackbed structures. Speaker Moderator Bryan C. Gee, Product Manager – Western Hemisphere, Tensar International Mischa Wanek-Libman, Editor, Railway Track & Structures Key topics and takeaways will include: Discussion of the benefits of mechanically stabilizing ballast and sub-ballast materials Design methodology for ballast and sub-ballast using both unbound and mechanically stabilized aggregate Rationale and methodology for incorporating geogrid for the mechanical stabilization of ballast How ballast mechanical stabilization using geogrid positively affects other aspects of the rail system, from lowering the risk of derailment to reducing operating and maintenance costs Use of mechanical stabilization to stabilize soft subgrades Optimization of ballast and sub-ballast structures using mechanical stabilization Testing and performance validation Design examples Project examples Practical design and construction considerations View Now Sponsored by:
