Under Sleeper Pads (USP) are tailor-made resilient systems designed to reduce track maintenance, increase the quality of the track and provide vibration mitigation by fixing elastic elements to the bottom surface of the sleepers.
The pads are designed to be attached during sleeper production by means of Pandrol USP Micro-Filament Fastenings (MFF®) technology.
A manufactured elastic product which is attached to the base of the sleeper
Micro-Filament Fastening bonding technique is designed to fix Pandrol USP onto fresh concrete during sleeper production and is compatible with all sleeper types
The under-sleeper pads can also be attached to sleepers at a post-production stage using glue
Suitable for all monoblock or bi-concrete and timber sleepers
Improvement of track quality via reduction of stresses on all track components and substructure due to a better load distribution over the track and its components both longitudinally and transversely
Designed to reduce life-cycle costs of track infrastructure by increasing longevity of track components, reducing rail corrugation and ballast thickness and minimising tamping frequency
Able to deliver vibration isolation up to 15 dB(v) and indirectly decrease noise by 1 dBA when compared to new track
Mitigation of detrimental effects and ballast stiffening due to win blown sand ingress
