Abstract (en)

[origin: EP0814197A1] The method involves placing the rail (3) on a level fixed base (1) so that it lies loosely on it and does not have mating shapes. The rail has cross ties (2) which form openings (61) between them which are at least partly filled with intermediate precast concrete bodies (4). The cross ties are separated from the concrete bodies by elastic acoustic material joints. The cross ties have a variable width along their length. The concrete bodies in the openings between the rails are placed loose on the base with a clearance gap (43) next to the rail. This forms gaps between them and the ties, which are filled with a foam type plastics for alignment of the rail.
