Supporting the Rail Industry with Tensar geogrid solutions for more than 30 years.

For railways around the world, line speed restrictions and expensive and disruptive track maintenance are frequently caused by poor track geometry and misaligned rails. Tensar’s trackbed stabilisation technology has been proven to substantially reduce track maintenance, being the subject of extensive independent research and development and approved by Network Rail in the UK and National Rail Authorities worldwide.

Using SmartRock to demonstrate the benefits of TriAx in ballast stabilisation

As part of Tensar’s extensive and innovative research programme, Pennsylvania State University used wireless 3D printed SmartRocks, equipped with accelerometers to monitor movement in three axes, embedded in ballast without TriAx and ballast stabilised with TriAx TX190L in a section of track, to monitor ballast particle movement under cyclic loading. Results demonstrated that TriAx reduced vertical displacement of the ballast particles by 85% and reduced particle rotation by up to 15 times, when compared with a non-stabilised section.

 

Helping you to cut construction, renewals and maintenance costs.

Compared with traditional trackbed construction, creating a mechanically stabilised ballast layer with Tensar TriAx can:

  • Maintain track geometry for longer

  • Reduce the rate of ballast settlement

  • Reduce maintenance induced ballast degradation

  • Extend the rail track maintenance cycle by a factor of around three

  • Stabilise ballast for over 20 years
