Abstract (en)
[origin: DE4439816A1] A process is disclosed for producing a concrete moulded body that carries the rails of a railway track and has at least one bearing outer surface provided with an elastic layer made of an elastomer or elastic plastic material. In order to ensure that the elastic layer adheres well to the concrete surface, the concrete moulded body is produced in a mould at least partially lined with an open-pored, elastic insulating mat (5) and then filled with concrete, so that after the concrete sets the insulating mat (5) is joined to the railway track supporting slab (1).
