TRACKELAST
Geogrids RK4.2c
Trackelast Geogrids play a major role in extending the maintenance interval for track ballast. Depending on the nature of the subgrade, geocomposites are deployed to:
- prevent pumping of subgrade fines
- control seepage and run-off
- stabilise a subgrade to improve bearing capacity and maintain track alignment
A geogrid may be introduced as a third component of the geocomposite to stabilise a poor subgrade and improve its bearing capacity.
