The side of the profiled USM®® 4015 track mat facing the ballast or concrete slab has a fabric-reinforced rubber covering layer that is resistant to abrasion, oil, ozone and the weather. On the underside of the mat are lenticular spring elements, which are made of high-quality natural rubber mixtures. Their particularly good dynamic properties are very effective in isolating vibrations. In contrast to non-profiled foamed products, each stud deforms under load to ensure the mats provide efficient protection against structure-borne sound and vibrations without any limits to functionality, not only under the standard test loads in laboratory-controlled conditions, but also under the actual loads generated by rail traffic.
The USM® 4015 track mat has an overlapping strip, which is vulcanised in place to seal the joints. The use of high-quality rubber and rot-proof synthetic materials for the fabric means the track bed mat does not suffer any loss of functionality over the entire time it is in place.
Mainly as a transition mat between elastically and rigidly supported sections of track to smooth out the difference in stiffness.
