The Benefits of Stabilizing Geogrids on the Railway

Maintenance of the trackbed and line speed restrictions have a significant impact on the schedules of workers and can be costly and disruptive for the public operators, industry, and asset owners.

Support railway tracks

Traditionally, railway tracks in the USA are made up of sleepers and rails that are supported by ballast and sub-ballast over the subgrade. A different option is 'slab track', which is used to support bridges, in tunnels as well as for high-speed lines. Rails are placed on pads, which are supported by the concrete base. For railway track maintenance, you can also hire dependable railway contractors in the USA via TRAC.

If sub-ballast and ballast are employed in conjunction, they create bearing capacity to help accommodate the dynamic load of trains. The ballast layer is usually 300mm thick, and sub-ballast size is determined by the strength of the subgrade.

Maintenance of railways in the USA

In general, maintenance on railways aims to correct bad track geometry and reduction in the horizontal and vertical alignment of the rails due to subgrade, ballast, and sub-ballast deformation, which usually leads to speed limits. Ballast must be tamped before being put on top of it as it is settling over time.

Savings for the entire life of the railway

With an ever-growing burden placed on infrastructure for rail, it is evident that there is a necessity to provide secure continuous, and efficient designs that provide the best value for money while minimizing environmental impact.
