How TrackTex Helped

TrackTex was installed on a cold October morning beneath the ballast as long-term effective remedy to this problem. TrackTex is a unique patented geocomposite and the result of over a decade of research by trackbed engineers and materials scientists.

Its specialist filter system improves trackbed quality over time and has been proven to significantly increase maintenance intervals. The use of TrackTex is the most cost-effective way of preventing and correcting mud pumping failure. Rainwater is unable to penetrate the microporous filter and is drained laterally to the side of the track Porewater below TrackTex is relived upwards under cyclic loading which aids residual slurry to dry out as the pore water is dissipated.

TrackTex conforms to the surface depressions in the formation layer and prevents the creation of slurry pockets. Fast installation rates reduce the construction costs and possession time.

 

 

What we did

On this project the use of a geogrid above the geocomposite was incorporated to provide additional stability. TrackTex can be used in conjunction with a geogrid and on this occasion a large aperture 30kN geogrid was placed above the composite prior to placing new ballast.

TrackTex was installed without the need for any specialist equipment.

On this installation a section of track was removed prior to installation however this is not always required. In most cases the track is simply lifted while the TrackTex is pulled into place.

 

Proven Performance

TrackTex has been proven to extend maintenance intervals by more than 25 times over conventional
geotextiles, it is for this reason that it is being increasing specified and installed.
