Rail pads are elastic polyurethane mats which are interposed between steel rails and railway sleepers to protect the sleeper top from wearing and impacting.
The starting stiffness of a rail pad is designed to not be high so that their relative deformation under the spring clip toe loads is greatly substantial. In this way, it can guarantees the rail pad maintaining in close contact with the rail despite of any vertical movements of the latter. In addition, the reason why rail pads made up of rubber or plastic is to dampen the shocks of vibration of a passing train.
Rail Rubber Pad
Rubber pads for railway tracks, also called elastic cushion, is used on concrete sleepers rather than on timber. It is used to reduce the fatigue cracking of the concrete ties. It can buffer the impact loads and insulate the rails from sleepers. Rail rubber pad, plastic sleeper bearing plate, cork rubber pad and wooden plate are common cushions, while rail rubber pad is superior in general performance. AGICO can supply rubber pads made from natural rubber, SBR, chloroprene rubber, HDPE and EVA.
The combination of grooved design and selected rubbers gives these pads their unique high resilience, robustness and anti-weathering properties.
Their superiority to those manufactured from other materials has been amply proven by their ability to reduce dynamic forces by up to 65% - a crucial consideration as railway systems worldwide adopt higher speed and greater axle loads.
The grooved rail pads positioned between the underside of the rail and top of the sleeper provide effective impact attenuation and extended life.
