Under Sleeper Pads are specially designed for application under concrete sleeper for ballasted track. They can be manufactured with a specific non woven layer for assembly into wet concrete during the sleeper production process.
What are the benefits of using an under-sleeper rubber pad?
Under-sleeper rubber pads (USPs) benefit railways by reducing maintenance costs and extending track life through vibration and noise dampening, better load distribution to protect ballast, and improved track stabilization, leading to fewer tamping cycles and smoother operation, especially on curves or transitions. They increase track quality, decrease ballast breakdown, reduce rail corrugation, and offer cost savings by minimizing wear and tear on track components, ultimately lowering life cycle costs.
- Ballast protection by dynamic load reduction
- Track stabilisation
- Improvement of track quality (decreasing of wearness)
- Possible reduction in the thickness of ballast to the creation of the track due to change of stiffness
- Vibration attenuation depending on the stiffness of the Under Sleeper Pad
