Definitions

  • the present invention concerns a roadway having a rail installed in it.
  • Such roadways are used in particular for joint use by road vehicles and railway vehicles especially light railway vehicles.
  • the rails for a railway are I beams supported by transverse sleepers on a bed of ballast on a prepared base. There a road crosses a railway, the surface of the road is level with the tops of the rails and the space between the rails is then built up. These rails have a high profile in that the width of the rail is very much less than the depth. For street railways or tramways a similar high profile rail is used. Thus tramways used a so-called phoenix rail which is generally an I beam but with a groove for flanges of the vehicle wheels formed in the upper flange.
  • Zahummensky in which rails are inserted in steel-lined channels in concrete panels with the rails being 7 centimetres deep and the panels 18 centimetres deep. A snag with such panel systems is that the panels have a tendency to settle or rock, in the Dresden system this is resisted by the rigidity of the phoenix-type track.
  • International Patent Publication WO 84/00391 there is described a phoenix-like rail consisting of an I-beam with a small foot and a large head. This is said to lead to a reduction in the number of sleepers and other bed structures because flanges forming the head substantially support the rail on a road surface.
  • the present invention provides a roadway for rail and road vehicles having a pair of rails recessed into a toad surface, each of which rails consists of a central squat bar portion and a pair of flanges extending integrally sideways from the top of the bar portion, the bar portion serving to provide a groove in an upper surface of the rail for supporting road wheels of a rail vehicle, which groove is for receiving flanges of the wheels, and each rail having a depth substantially less than its width and having its bar portion installed in a relatively shallow recess preformed in the road surface to a depth so as to receive the bar portion with the flanges effectively supporting the rail.
  • the flanges serve the functions of spreading vertical loading, gripping the road surface to resist cross-loading and to minimise damage to the roadway due to water seeping down the sides of the bar portion.
  • the flanges can have ridges to bite into the roadway and/or a sealant can be used to provide a water seal and to absorb sideways loading. Where sideways loading is expected to be very large, sections of phoenix track can be used.
  • Figure 1 illustrates on a large scale a rail 11 in a shallow recess 12 in a roadway 14.
  • the recess can be, for example 4 centimetres deep and 10 centimetres wide.
  • the rail has a central bar portion 15 which is generally a regular trapezium in section but with a groove 16 for a vehicle wheel flange in the wider surface which in use is the uppermost surface of the rail. Extending integrally sideways from the bar portion, there is a flange 17 on each side of the rail.
  • the recess is preferably cut out by suitable cutters such as disc or other cutters cutting the sides of the recess and such as a plane or other cutters removing the material remaining between the cut sides of the recess.
  • the recess is then partially filled with a suitable material 18 so that when a rail is inserted in the recess the rail can be settled into the material 18 so that the vertical loading is effectively taken by the rail being suspended from the flanges.
  • the rail can be of steel, iron or another material rolled, extruded or otherwise fabricated into the squat T-shape illustrated.
  • the rail can be secured in place by mechanical or other means such as an adhesive bond which preferably has a degree of resilience as is provided by Corkelast. It is possible to provide ribs or a shallow groove in the underside of each flange to improve the sealing and the resistance of the rail to sideways movement.
  • Rails can be welded or otherwise joined end-to-end to form a continuous track and can be laid under tension to avoid thermal expansion problems. As shown in Figure 2, a pair of rails will normally be used and a pair of recesses can be cut simultaneously using ganged cutters to ensure correct spacing. Cross ties not illustrated can be provided at intervals to form gauge defining devices and these can be recessed below the roadway surface.
  • the space between the rails 11 is built up to the top of the rails by a thin layer of tarmac 20 or other road facing material. It would be possible to recess the flanges slightly in the road surface so that they are substantially flush with the roadway and then merely fill the seam alongside the flanges with tarmac or the like. It would also be possible to have the flanges slightly down from the top of the rails with tarmac or other material on top of the flanges to minimise the amount of metal exposed.
  • Figure 3 illustrates a junction piece which would be cast or otherwise formed and comprises two rails 21 and 22 crossing at an angle with the grooves in the two rails extending across the central intersection 23. Where more complicated arrangements are involved such as junctions, special provisions might be made
