<p>A ballastless superstructure, preferably Vignoles rails (1), has rails (1), which are detachably connected to supports (2). Each support (2) has at least two rails (1). On the rail (1), there is on each side of the rail web (9) a sound-adsorbing device extending optionally to the rail head (11) and optionally to the rail base (10). The sound-adsorbing device being formed with a coating (8, 12; 19, 21), which is adhesively adjoined to the rail (1), covers the rail web (9) and the rail base (10). The coating (8, 12, 19, 21) is composed of particles (23), which are bound by a binder (24), whereas the particle size ranges from 2 to 8 millimetres, and optionally by fibres, especially glass fibres. The rail is treated with a water jet at pressure of 40 bars, preferably 400 bars at least. Then, the coating is adhesively adjoined to the rails.</p> |
