Empirically-backed Predicitive Modeling

By creating a more stable and stiffer layer under track, the GEOWEB soil stabilization system is a proven solution for ballast stability problems.  The 3D GEOWEB system is beneficial in problematic soft soil areas, and offers performance and constructibility benefits not delivered by 2D planar geogrids or Hot Mix Asphalt (HMA).  Extreme AAR-TTCI field testing proved the GEOWEB system’s exceptional benefits for stabilizing track subballast subjected to repeated heavy rail loading.

GEOWEB Benefits for Track Ballast Reinforcement

Railway engineers worldwide have relied on the GEOWEB technology to create high-stiffness roadbed foundations under track, and at bridge approaches, diamonds and turn-outs. The GEOWEB system is extremely effective in stabilizing track subgrades, and has even more beneficial value in soft soil areas.

  • Reduces Rock Size and Cross-Section Thickness: Rock confined in the 3D GEOWEB structure replaces expensive larger stone, reducing aggregate size by up to 10X. The aggregate thickness & cross-section can be reduced by up to 50%.
  • Less Down-Time: The GEOWEB material can be quickly installed to make any necessary repairs and minimize costly track disruptions.
  • Installation Benefits: Due to the ease of installation, the GEOWEB material can be installed by the railroad’s on-site crews.

GEOWEB 3D Benefits Compared to 2D Geogrids

GEOWEB 3D Benefits:

  • Reduces ballast depth 2-3 times.
  • One-step direct deployment over soft soils.
  • Limits differential and long-term settlement through hoop strength and active/passive resistance.
  • Ideal for difficult or limited access.
  • Fast deployment = limited down-time.
