Abstract (en)
[origin: WO2005098136A1] Disclosed is a ballastless superstructure for railborne traffic, comprising prefabricated concrete support plates (1, 1a) which support at least two rails (4), have a greater length in the longitudinal direction of the rail than in the direction extending perpendicular thereto, and are provided with at least two rectangular continuous recesses (2, 2a) that are open towards the ground. Said support plates rest on a foundation (13, 14), e.g. a concrete foundation, via a rubber-elastic layer composed of rubber granulate that is bonded by means of a rubber-elastic bonding agent and via a casting compound (12) containing hydraulic and latently hydraulic bonding agent. The rubber-elastic layer (15) is leveled with the aid of a pasty separating agent (20), especially paraffin, on one or several surfaces (16, 17) facing the casting compound while the recesses (2, 2a) taper in an upward direction.
