Definitions

  • the invention relates to a method for applying a road-surface material composed of an asphaltic mixture of bitumen and small stone fragments which enclose cavities. This is, in particular, the road-surface material at the joining interfaces encountered in a road surface.
  • a method for covering such a joining interface between a bridge abutment and a bridge in a road is disclosed in EP-A-506196.
  • an asphaltic mixture is used which has a high percentage of enclosed open cavities (drainage asphalt).
  • the asphaltic mixture having a relatively large quantity of enclosed cavities appears to be less resistant to such conditions.
  • the flexibility is fairly low, as a result of which the expansion differences may be inadequately absorbed.
  • the capacity to absorb impact stresses without permanent deformations occurring is too low.
  • EP-B-642 has attempted to offer a solution to this problem.
  • the joining interface is filled with a mixture of aggregate parts and a bituminous binder with a rubber base.
  • Such a mixture is less suitable for high traffic stresses in view of its viscoelastic behaviour resulting from of the high proportion of bitumen. It has been found that such improvements do not offer an adequate solution with the increase in traffic stresses.
  • the object of the invention is therefore to provide a method which is adequate in this connection. This is achieved by means of a method for covering the interface between a bridge abutment and a bridge in a road with a surface material, comprising the steps of:
  • the combination of a very open asphalt and the plastics compound present therein has various advantages.
  • First of all drainage asphalt has an improved bearing capacity compared with a conventional asphaltic mixture.
  • the essentially equally graded small stone fragments are encased in a bituminous mortar which provides for the cohesion of the mixture.
  • the small stone fragments are pressed against one another so that a supporting stone skeleton is produced, which provides for a good load transfer from the road surface to the underlying supporting structure. Because, however, the bituminous joint between the small stone fragments can undergo only limited deformation, the cohesion of the layer would be lost in the event of fairly large deformation and crack formation occurs (fatigue effect), as explained above.
  • the plastics compound thus appears to provide a predictable and stable behaviour of the combination, even in the case of the relatively large movements which occur in road interfaces.
  • a further improvement may be obtained by applying a curable plastics compound which, during the curing process, produces a small amount of foam (small gas bubbles).
  • the surface material is pre-eminently suitable for the interface between a bridge and the adjoining bridge abutment.
  • the asphaltic mixture can be applied on either side of and above the interface between the bridge abutment and the bridge.
  • the adjoining road-surface sections may have a different composition.
  • the asphaltic mixture can be applied over a bridge deck and the adjoining road sections and also over the interface between bridge deck and at least one road section, the plastics compound being introduced at least at the interface.
  • a boundary can be provided in the surface material on either side of the interface before the plastics compound is introduced.
  • the plastics compound can also be introduced into the asphaltic mixture covering the bridge.
  • the traffic surfaces thus obtained must be very resistant to the fatigue stresses which occur as a consequence of the passing traffic. Said fatigue stresses comprise local deflections which may ultimately give rise to crack formation.
  • the plastics compound introduced into the asphaltic mixture imparts a higher stability to the covering material thus manufactured, in combination with a certain degree of flexibility.
  • the invention also relates to a road-surface structure comprising an interface between a bridge and a bridge abutment, at which interface a surface material is situated which comprises an asphaltic mixture of small stone fragments having an encasing of bituminous mortar which is situated on the surface of the small stone fragments, by means of which encasing the small stone fragments are attached to one another with the inclusion of residual cavities filled with an elastic plastics compound.
  • the plastics compound can only be introduced into the asphaltic mixture at the interface.
  • the asphaltic mixture filled with plastics material can be enclosed between two boundaries extending through the surface material.
  • the surface material extends continuously over bridge, interface and bridge abutment.
  • Figure 1 shows a section through the surface material.
  • Figure 2 shows a section through a joining interface.
  • FIG. 1 shows a surface material according to the invention.
  • Said surface material is composed of an asphaltic mixture known per se (drainage asphalt) composed of small stone fragments 1 and a bituminous mortar 2 which is situated on the surface of the small stone fragments.
  • bituminous mortar 2 By means of this layer of bituminous mortar 2 on the small stone fragments 1, the latter are attached to one another, as a result of which a rigid stone skeleton is produced which can transmit stresses in a suitable manner to a foundation via the contact faces between the various small stone fragments.
  • the bituminous mortar gives the skeleton a slight degree of flexibility, as a result of which said skeleton can yield to a limited degree under stress. If a certain degree of deformation is exceeded, as may occur, for example, on steel bridge decks or in joining interfaces between a bridge deck and a bridge abutment, the skeleton deforms plastically, as a result of which cracks may be produced and small stone fragments may ultimately break away under the influence of the vehicular traffic.
  • the cavities between the small stone fragments with their bituminous mortar layer are filled with an elastic plastics compound 3 which is capable of causing the skeleton to yield elastically even for fairly large deformations so that the skeleton can return to its original shape.
  • Said elastic plastics compound 3 may be composed, for example, of polyurethane or epoxy. A material which can be cured by means of UV light can also be used.
  • the plastics compound 3 can be introduced into the cavities between the small stone fragments 1 in the form of a two-component mixture. Said mixture can easily penetrate all the cavities, and can then cure as a result of the two components reacting with one another.
  • Figure 2 shows the joining interface between a bridge abutment 4 and a bridge deck span structure 5 which rests on bearing 6.
  • a sealing profile 7 has been provided in a known manner between bridge abutment 4 and bridge deck span structure 5, as well as a steel plate 8 which is coated on the top and bottom with a sliding layer of bituminous material 13.
  • the joining interface is provided with a continuous layer of surface material 9 composed of a very open asphaltic mixture composed of small stone fragments with a bituminous mortar (drainage asphalt).
  • a bituminous mortar drainage asphalt
  • the open cavities of the asphaltic mixture in the vicinity of the joining interface have been filled with a cured elastic plastics material.
  • the asphaltic mixture 10 according to the invention is therefore situated at the point of the joining interface.
  • Said asphaltic mixture is pre-eminently suitable, on the one hand, for absorbing stresses exerted by the road traffic and, on the other hand, for absorbing the relative movements resulting from expansion movements of the bridge deck span structure.
  • the asphaltic mixture 10 may be enclosed by boundaries 11, 12 which are intended to enclose the plastics material against leakage during introduction so that the mixture according to the invention is produced only at the point of the joining interface.
  • the asphaltic mixture could also be provided in a slot recessed or provided at the point of the joining interface and then filled with the plastics compound. It is also possible for bituminous topping layers to be present in addition between the concrete bearing structure and the mixture according to the invention.
