RAIL PADS
    AND BASE PLATE PADS
Using elastic rail pads and base plate pads in special rail fastening systems exploits the load-transferring effect of rails. Acting forces are distributed across several support points of the applied wheel load, so that stress is greatly reduced on the directly affected rail support point.

 
 

Rail pads and base plate pads

 

Short description

The product consists of closed cell microcellular foamed EPDM. Due to the material properties, the product has outstanding resistance to aging and weathering and is characterized by minimal water absorption. Elastic Rail Pads are installed directly beneath the rail base to protect the track bed structure and increase elasticity in ballast beds. Elastic EPDM rail pads can be manufactured in a variety of dimensions for different rigidities as per client requirements for different needs, ranging from metros and tramways through to high-speed traffic, thanks to their microcellular structures. Elastomers with a rigidity between 5–200 kN / mm, depending on area of use and low frequency response between 1 Hz and 30 Hz – dynamic stiffening with stiffening factor of about 1.1 are further advantages of the product.

Short description

The elasticity required for ballastless track systems is guaranteed by highly elastic Base plate Pads and installed between the ribbed base plates and the supporting concrete slab with a spring rigidity of c = 5 - 60 kN / mm. This ensures a load-spreading effect in the rails and greatly reduces any vibrations and structure-borne sound. A low frequency response between 1 Hz and 30 Hz and an excellent rebound elasticity (> 60 %) are some properties among other advantages.
