Under-Sleeper Pads product overview
The systems are easy to install, maintenance free and compatible with all types of track design; with their use also proven to reduce the life-cycle cost of the railway.
When USPs are installed, the stress within each sleeper is reduced due to a more even distribution of axle load.
- Contact area between the ballast and sleeper is also increased, resulting in a more homogeneous track quality.
- USPs are made from high-quality resin-bonded rubbers. Depending on the project, the design parameters can be adjusted to achieve a vibration attenuation target whilst also ensuring track quality.
- Across all ballasted track scenarios, designed to improve track quality, give better load distribution and provide vibration reduction, constructed from high-quality materials and resistant to any prevailing conditions.
