Track Ballast Stabilisation
Track maintenance work and line speed restrictions significantly affect schedules and are expensive and disruptive to the public, train operators and asset owners. Much of it is down to poor track geometry and a loss of vertical and horizontal alignment of the rails, caused by ballast deformation.
Certification and Approval
TriAx TX190L geogrid has been approved by rail authorities, including Network Rail, for improving the performance of ballasted track.
How Tensar geogrids can help
Adding a layer of Tensar TriAx Tx190L geogrid means that the ballast material partially penetrates and projects through the apertures. This creates a strong and positive interlock to limit lateral movement under loading and by doing so, the settlement rate is reduced. The durable polypropylene grids have been proven to function in ballast for at least 20 years, too – offering a truly long-term solution.
A proven solution
Having been used for ballast stabilisation for well over 25 years, Tensar geogrids have been the subject of extensive independent research and development both in laboratory and field conditions; this has led to them being approved by Network Rail in the UK and National Rail Authorities in many countries.
