EVA Railway elastic Pad
Rail EVA pad function to reduce fatigue cracking of the concrete ties, believed to be driven by impact and vibration from the passing train.
The Rail EVA pad act in two ways: they diminish shock or impact loads by providing compliance, and they reduce (by isolation and perhaps by damping) resonant vibrations excited in the concrete ties (lowest resonant frequency about 200 Hz) and accommodate vibration deflections in the rail sections between the ties (about 0.12mm amplitude, 1000 Hz).
GNEE's EVA Rail Pad Key Features
- Suitable for Light Rail systems, up to heavy freight lines
- Impact attenuation
- Extended track life
- Cost effective
We can supply rail pad with a thickness ranging from 5mm to 25mm thick. Pads made of metal bonding are used to reduce extensive vibrations.
