Railways, new tracks and track renewal
Railway tracks is areas with soft soils and high ground water levels are susceptible to settlement and requires regular maintenance for track alignment and safe transportation. Railway Track with Typar Geotextile SF below ballast provides stabilization and separation to reduce impact of dynamic loading.
- Typar SF avoids ballast contamination by pumping effect due to dynamic loading.
- It allows better compacting and aggregate saving.
- Typar SF retains soil particles without clogging.
- It ensures longer service life.
How Typar® Geotextile Work
Railway Track with Typar Geotextile
Separation: TYPAR SF Geotextiles separate soil from the ballast aggregate stone, preventing intermixing that would otherwise result in reduction of bearing capacity. The main application areas of a geotextile used as a separator are in road and railway projects. The use of the geotextile preserves and improves the integrity and function of the different materials. Two mechanisms occur when an aggregate base is laid over a soft subsoil and a vertical load is applied
Drainage: TYPAR SF Geotextiles opening size and hydraulic properties allows passage of precipitation and ground waters while restraining soil to avoids clogging of aggregate.
Stabilization and Reinforcement: TYPAR SF Geotextile’s high initial modulus provides tensile strength to increases load carrying capacity of weak soils.
