Method for producing a superstructure for railways

摘要

A method is used to produce a superstructure for railways, consisting of slabs laid on the formation, preferably of a jointlessly produced slab of concrete or special concrete with plastic and/or bitumen additives, optionally with an upper levelling layer of fine asphalt concrete. The track grid consisting of tracks screwed to concrete sleepers is bonded to said slabs by means of a bitumen- and/or plastic-based casting compound. In order to provide a superstructure of this type in which the track grid can be readily bonded to the baseplate by the casting compound, in particular also in banked curve regions, parallelepipedal precast concrete parts (4) are inserted into the spaces between the sleepers (2) and bonded to the sleepers (2) and the slab (1) by means of the casting compound (10) (Fig. 2). <IMAGE>
