Overview
Background & policy context:
The main objective of the project was a standardization of a ballast superstructure with Under Sleeper Pads (USP) in order to enable all UIC Railways to benefit from the advantages of USP within as many fields of applications as possible.
Objectives:
- Costs/Superstructure: Working out the positive influence of using USP when it comes to saving costs during construction, renewal and upgrading of railway lines without any disadvantages concerning track availability and life-cycle-costs
- Costs/Substructure: Investigating the influence of using USP in situations with inhomogeneous subsoil with regard to track availability, life-time and costs
- Special Applications: Thoroughly assessing the benefits of USP for the use in transition areas, on short bridges, in small-radius curves and for turnouts and extension joints
- Vibrations: Investigating the benefits of using USP as a protection against vibrations, structure-borne noise and air-borne noise
