Abstract
The present invention relates to an arrangement for crossings between a road and railway, where the road structure is interrupted between two edges, between which is positioned at least one railroad track, the arrangement comprising two rails supported by a row of sleepers arranged substantially perpendicular to the rails, said sleepers resting on a foundation, outer slabs being deposited in the area between the rails and the respective edges of the road structure, and a center slab, preferably divided up into sections in the longitudinal direction of the track and positioned between the rails forming the railroad track, which slabs are provided with their top surfaces level with the top surfaces of the rails and the top surface of the road structure, and elongated supporting elements provided to extend along said edges of the road structure. The elongated supporting elements comprise in combination a bottom surface provided to rest on the foundation, a first side edge which is provided to face the road structure, forming a support for the same, a first upper surface connected to said side edge, a positioned second upper surface positioned at a distance from the first upper surface which substantially is level with the first upper surface, between the both upper surfaces and extending along the supporting element, a groove open in the upper surfaces and provided to form a water outflow, a second side edge opposite to the first side edge, forming a support for the outer edge of the respective outer slab, so that the elongated supporting element forms a support for the road structure, a base surface level with the road and the outer slab, a support for the outer slab and a water outflow for water preferably from the road.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
