Helping rail authorities stretch budgets further  

Rail Authorities across the globe face the monumental task of building and maintaining the railway networks that move passengers and freight across nations and continents. Rail Engineers designing new railway seek to deliver safer, better, longer-lasting railways more economically, more sustainably and with greater climate resilience. Those responsible for maintaining existing rail networks face a widening gap between the needs of a deteriorating network and squeezed maintenance budgets. 

With materials and labour costs continuously rising and the scope of their responsibilities consistently expanding, how do rail authorities keep up? Tensar helps railway authorities stretch trackbed, earthworks, and bridgeworks budgets further, by using our proven technologies supported by Tensar expertise and software.

Earthworks and Bridgeworks  

Almost all rail projects involve the construction of retaining walls, road embankments, bridge abutments, and other features. Tensar has a range of TensarTech earth retaining systems for retaining walls, steep embankments and bridge abutments. These solutions offer major cost advantages and construction programme advantages over alternative construction methods. They also enable use of re-cycled or site-won fill materials to keep down costs and minimise local impact.  

Additionally, Tensar has innovative solutions for the construction of embankment foundations over weak soils. These can be quicker to construct, with a reduced land take and controlled settlements.

Even Better Value

An efficient rail network must maintain design speeds and minimise service disruptions for major maintenance operations. The quality and durability of the trackbed are critical, both in determining safe operating speeds and in minimizing maintenance related disruption.

In new track and track reconstruction works the bearing capacity and stiffness of the trackbed foundation can be improved by incorporating Tensar stabilisation geogrids into the sub-ballast layer. In ballasted track, the time between necessary tamping maintenance can be significantly increased by incorporating Tensar stabilisation geogrid in the base of the ballast layer. Ballast degradation and track settlements are reduced, maintaining track speed and extending maintenance cycles.

Rail Track

What if you could design higher performing trackbed more sustainably and with greater resiliency - without increasing costs? What if you could extend trackbed service life or greatly extend the periods between routine maintenance?    

The rail track is the primary focus of a railway, but it is supported on major earthworks, embankments and bridgeworks. Structural and geotechnical engineers building railway infrastructure are faced with the same pressures: to deliver more for less. They also seek to design more economically, more sustainably and with greater resilience.  The goal is to construct railway embankments with a reduced footprint, more quickly and with reduced carbon emissions or for a rail bridge or over bridge decks to be constructed bank seats bearing directly on lower-cost reinforced soil abutments using re-cycled fill. Tensar has proven innovative solutions for trackbed, earthworks, and bridgeworks - supported by Tensar expertise and software.

Design with confidence, from anywhere.

The TensarPave design program allows the design engineer to rapidly produce pavement designs, for both paved and unpaved roads, using Tensar geogrids to stabilise the unbound layers in order to maximise the costs benefits that can be attained by reducing the pavement thickness.
