Definitions

the invention relates to a railway superstructure according to the preamble of claim 1.
Solid carriageways for track gratings made of asphalt or concrete which have proven their worth in road construction, are intended to enable future rail traffic with higher loads and higher speeds.
the invention has for its object to propose a means that a full-surface load-distributing support of the sleepers and their subsequent position correction on the relatively coarse surface of the solid substructure enables, but resistant to environmental influences - water, oil, aggressive liquids, temperature - as well as abrasion, vibration and aging, the track laying is possible in all weather conditions and is cheap to manufacture.
the advantage of the inventive solution is that the unevenness of the surface of a solid base layer made of asphalt, asphalt concrete, concrete and / or the underside of the sleepers is compensated for and the compensating film has a vibration-damping effect, but it also allows for a displacement of the sleepers after initial positioning without the compensating film to destroy.
Wooden or concrete sleepers withstand such abrasion less than steel sleepers; On the other hand, steel sleepers vibrate more.
Films made of gas-filled foamed or rubber-like material, which behaves elastically and is so compressible that the surface roughness can be compensated, are ideal as a threshold underlay.
Closed-cell foam cannot absorb liquids and is therefore not destroyed by aggressive media or when water is absorbed by frost.
Low density PUR foam has proven to be an acceptable material; it is also resistant to UV light.
a bitumen-impregnated, water-repellent cardboard with sufficient tear strength and low demands on load-bearing capacity and aging could also suffice. Tests also showed the usability of bituminous natural cork.
the compensation foil could already be attached under the threshold at the factory. A glue-containing coating of the compensation film would make it easier to apply under the threshold.
the threshold is provided with adhesive and the compensating film is given a protective coating to protect it from transport damage until both parts are joined together on the construction site.
a concrete sleeper is glued under its support surfaces with a 5 mm thick PUR foam film using a weatherproof contact adhesive.
the film has a modulus of elasticity of 10 MPa and a density of 25 kg / m3 and has approximately 90% closed-cell gas pores.
the soft compensation film is protected from transport damage with a tear-resistant cover.
the threshold After the threshold has been positioned for the first time on the solid asphalt surface at the intended place of use, it can be raised and relocated again and again without impairing the function of the compensating film.
a reversible elastic threshold offset of max. 0.5 mm determined by lateral displacement forces. The position of the leveling film on the solid asphalt layer or under the threshold did not change.
