Railway Track Ballast Support

Railway Track Ballast Support

Tensar biaxial geogrids provide an extremely cost-effective solution for the reinforcement of ballast over a soft subgrade, bringing significant benefits to the railway engineer. There are two major application areas for the use of Tensar biaxial geogrids - within and beneath railway track ballast:

• Direct ballast reinforcement to reduce the rate of track settlement and hence reduce maintenance cycles.

• Reinforcement of a granular sub-base layer beneath the railway ballast to increase the bearing capacity of the track foundation.

• An alternative to increasing the depth of ballast, or adopting chemical stabilisation.
• Reduction of the rate of permanent settlement.
• Improved rail ballast performance allows consistent high speeds to be achieved.
• Avoids the need for excavation of soft soil and replacement with thick layers of imported fill.
