Amorim Cork Solutions supplied its Amorim Rail Under Ballast Mats (UBMs) for a railway infrastructure project in Pampilhosa do Botão, Portugal, where specific structural conditions required an enhanced approach to vibration control.

The application was placed in a structurally demanding section of the track, specifically within a transition zone adjacent to a bridge. These areas present engineering challenges due to changes in track support stiffness and the different dynamic responses of adjacent structures. Such variations can influence how dynamic loads and vibrations are transmitted through the track system, making vibration mitigation an important consideration in the design.

Selected to address these specific requirements, Amorim Rail UBMs provide an elastic and resilient layer beneath the ballast, helping to reduce vibration transmission to the underlying structure while maintaining the mechanical performance required under repeated railway loading.

Under Ballast Mats

Installed beneath the ballast layer, these mats help attenuate vibrations generated by passing trains, reducing their transmission to the supporting structure and surrounding environment. Their performance relies on the ability to withstand repeated dynamic loads while maintaining stable mechanical properties throughout their service life.
