Insert pads for sleeper bases
Slab track systems require sufficient elasticity to activate the load distributing characteristics of the rail. In this respect, there are a wide range of possibilities for employing elastic components.
Elastically mounted sleeper blocks have the advantage reducing the amount of airborne noise emissions, due to the additional mass through which the vibration must travel. The larger elastic load bearing surface also results in lower edge pressure.
Dual-level elasticity additionally serves to mitigate the amount of pressure exerted on the insert pads and results in lower wear on the rail fasteners. As Getzner insert pads can be manufactured with any desired stiffness, it is possible to meet a very diverse set of needs. This system is generally employed in tunnel sections of various types.
