Definitions

  • car road means any road designed for road traffic, among which pedestrians, cyclists, passenger cars, trucks and motor cycles.
  • NL-A-1007815 discloses a rail structure wherein two parallel rails are each located in a separate trench into an attachment layer of a porouss starting material with a relatively large percentage cavities, such as ZOAB (Zeer Open Asfalt Beton; Very Open Asphalt Concrete), wherein said cavities are filled at a later time with a curing stiffening agent, e.g. based on cement.
  • the rails are fixed within the trenches by means of a plastic pouring mass.
  • the attachment layer can relatively quickly and simply be applied with the aid of e.g. known réelle spreading techniques, such that the drive plane is quickly available for the car traffic. Since the road paving provides the foundation, costs are reduced.
  • the rails have to be provided, set and fixed in situ, which is cumbersome and inaccurate. Also a special top layer structure is required to stabilise the trenches for the rails. This top layer structure can provide no sound reduction.
  • DE-U-29611725 discloses a rail structure with mutually coupled rails, flush with a car road, wherein aside the rail a row is provided of concrete edge elements, extending the complete height of the rail. Each edge element is glued to the concrete sub structure by special mortar. The object of this prefabricated edge element is avoiding collapse of the road surface directly adjacent the rail and the instabilities because of that.
  • EP-A-0.737.778 discloses a sound demping rail structure wherein the two rails are each located in a seperate trench in a concrete or steel foundation. Between and adjacent the rails a layer of sound absorbing material is provided, such as ZOAB. This rail structure is not located in a car road. Data about the fixation of the rails are not available.
  • US-A-5513797 discloses the use of special formed rails for combined infrastructure systems with a cement concrete rouad structure wherein afterwards the trench for the rail is machined.
  • De rail has at both sides projecting flanges at its top which are adapted to bear at the road structure and from which the in the trench in the road surface located rail will be suspended. These flanges provide a relatively large contact surface with the road structure for a proper load distribution.
  • Fig. 4 of this US discloses an embodiment for a relatively weak road structure, for which first a prefabricated cement concrete beam with trenches of approx. 5 m length is located in the cement concrete road structure. Then the rail is located in the beam with trenches. Since the beam and the rail are separately provided subsequently, hughe setting operations are required in situ.
  • the object of this invention is an improved rail structure, particularly for application to a car road.
  • the object of this invention is a rail structure wherein the rails are located, preferably fixated, each in an own trench in a road paving, wherein said road paving preferably at least partly provides the rail foudation.
  • the road paving and/or the substructure for it is preferably not provided as (reinforced) cement concrete or other ridgid material (possibly poured in situ or built from prefab elements).
  • the road paving and/or the substructure for it, or at least a (substantial) part thereof is provided in non-rigid material, e.g. asphalt concrete or a material with processing characteristics (e.g. application speed, curing time to drivability by cars) comparable to those of asphalt concrete.
  • a rail way flush with a car road wherein two parallel rails are each provided in a trench in the road surface, wherein the rail is embedded in embedding material and wherein
  • the wall element is part of a structure enclosing said rail at at least one of the longitudinal sides and the under side.
  • the rail can be housed in an open tray structure, open at the top.
  • the wall or tray structure is longitudinally divided in (tray like) elements.
  • the gap between these elements is preferably filled with a preferably flexible filling material, such as a mortar, with which possible residual expansions can be accomodated.
  • a preferably flexible filling material such as a mortar, with which possible residual expansions can be accomodated.
  • the upper edge of the wall of trench structure is preferably at the same level as the road surface plane.
  • asphaltt concrete also other paving materials like gravel or stone like granules, bound with bituminous (like) or thermoplastic binders, are meant.
  • the wall element offers due to its large contact area a proper load transmission between de rail and the car road.
  • the corners of the tray section can be adapted/optimised for a larger stability and/or an improved load transmission.
  • the invention also relates to the prefab element as such, e.g. adapted for application in the railway structure according to this invention.
  • Fig. 1 shows the section of a partly illustrated drive lane with flush railway
  • Fig. 2 shows a cross section of the prefab arrangement of this invention.
  • the car road 1 is build is disclosed in NL-A-1007815 (incorporated by reference), and corresponding reference signs are applied to indicate corresponding parts, while also reference is made to the section of NL-A-1007815, from page 3, line 8 to the end for a discussion of said parts. It will be appreciated that the layer of cement concrete is now absent.
  • the prefab assembly 10 of fig. 2 contains the rail 2, the embedment agent 6 and the tray structure 11.
  • the embedment agent 6 can be a plastic pouring mass, possibly containing vibration damping filler means.
  • the tray 11 is made of (reinforced) cement concrete, is relatively thick walled and provides two side wall and a bottom element. However it can also be made of another material, e.g. steel plate, polymer concrete, plastic. Also another shape of the tray 11 is feasible. Besides the tray can be thin walled.
  • One of the objects of the tray 11 is to sufficiently protect against damaging the relatively weak material of the edges of the trench 3. For that the upper edge of the tray 11 is preferably substantially at the same level as the driving plane 5.
  • This assembly 10 can as a whole be installed in a trench 3 made in an exsisting car road.
  • Another example is the situation where first the foundation of the road is applied, possibly including the first lower layers of the paving from e.g. asphalt concrete. On top of that the assemblies 10 are located and glued, possibly into a shallow trench. Thereafter the rest of the paving is applied over the height of the part of the assembly 10 projecting above the trench.
  • first the foundation of the road is applied, possibly including the first lower layers of the paving from e.g. asphalt concrete.
  • the assemblies 10 are located and glued, possibly into a shallow trench. Thereafter the rest of the paving is applied over the height of the part of the assembly 10 projecting above the trench.
  • the assembly 10 is fixed in the trench with a binder that fills the space between the tray 11 and the trench 3.
  • the rail 2 and the tray 11 are substantially continuous.
  • the rail 2 preferably has an undivided length.
  • the rail 2 has a length in the order of 15 m
  • the elements of the tray 11 have a length in the order of not more than 2 m, preferably shorter than 1 m, such as about 10-20 cm.
  • the combination of ZOAB or another porous, preferably bituminous starting material with relatively high percentage (open) cavities and curing stiffening agent for the attachment layer 4 can e.g. be replaced by a layer of carbon binder.
  • the dured stiffening agent could be eliminated from the layer 4 or could be replaced by a curing stiffening agent that is not based upon cement.
  • the ZOAB in the layer 4 could be replaced by another asphalt material with equivalent applicability, e.g. without or with only a relatively small percentage cavities.
  • the paving layer 7 and/or foundation layer 8 can be absent or made of other material.
  • the rail 2 can bear onto the bottom of the tray 11 through a damping pad or such damping means.
  • the tray 11 could be without bottom, such that the bottom of the prefab assembly is provided by the embedding agent 6.
