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:

• Reducing ballast deformation through the mechanical stabilisation of the ballast layer.

• Improving track foundation through the mechanical stabilisation of the sub-ballast layer.

• 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.
• Reduced maintenance due to a proven increase in the intervals between maintenance interventions.
