Definitions

  • the invention relates to a method for producing bituminous fastenings or for stiffening existing bituminous fastenings of traffic areas according to the preamble of claim 1 and 2 respectively.
  • bituminous layers Fortifications of traffic areas consisting of bituminous layers are usually applied to a substructure and consist of a framework made of minerals, for example grit, the cavities of which are filled with bitumen or tar.
  • bituminous mix which consists of mixtures of bitumen or tar with minerals, is usually produced and applied to the substructure in the desired thickness.
  • bituminous layers have only a limited load-bearing capacity, in particular with higher wheel loads and / or summer temperatures.
  • the properties of the bituminous binders are temperature-dependent, so that their strength decreases with increasing temperature.
  • bituminous layers can be increased by using harder binders as additives to the bitumen or tar and by changing the grain composition of the mineral substances.
  • harder binders are, however, only possible to a limited extent, since bituminous layers with harder binders can no longer reduce the temperature tensions at lower temperatures, so that cracks occur. Such coverings are therefore not winterproof.
  • bituminous layers cannot be increased indefinitely even by the type of grain composition of the mineral substances. It is known that bituminous mixtures of broken grain with the largest possible grain diameter are more stable than fine-grain mixtures. Both the mixing technique and the distribution and compacting of the mixtures with rollers, however, place limits on the use of low-sand coarse-grain layers. In areas where coarser rock material is missing, predominantly sands have to be used to produce the bituminous layers, especially the base layers, which leads to layers with a lower load-bearing capacity.
  • the object of the invention is to provide a method of the type specified, according to which both new and existing fastenings can be stiffened.
  • this object is achieved in a method of the generic type by the characterizing features in claims 1 and 2, respectively.
  • inventive method vertical plugs or pins made of rigid material are introduced into the intermediate layer, which have the effect of supporting stamps and thereby the strength and the deformation resistance of the intermediate layer to traffic loads or the like. increase considerably.
  • DE-C-528117 discloses a method for increasing the friction of bituminous road surfaces by roughening, in which grooves are pressed or cut at a distance from one another in the top layer of the road, for example with the aid of a heatable pressure roller or a milling cutter.
  • the road is then cleaned and the dry road surface covered with a coal tar skin by ordinary surface depletion.
  • the road is sprinkled with hard stone chippings of 3 to 8 mm grain, which is then swept into the grooves, in which the grain forms an intimate mixture with another scattered fine grit or sand and the tar, which is then rolled off.
  • a road is thus obtained which contains a low-void mixture of tar-chippings in the grooves, while it is provided with a thin tar coating between the grooves.
  • the holes or depressions which receive the hardening material can be introduced into the layers at the desired distance. They can be distributed over the entire layer or even only over areas of the layer. For example, they can be placed in zones with particularly high loads, for example, on highways only in the heavily used right lane and not in the left passing lane.
  • the stiffening plugs or pins can also be attached in the areas of the lane that are overrun by the wheels and in which ruts often form.
  • the size, number and depth of the holes or depressions depend on the respective stresses.
  • the holes are pressed according to claim 1 in the just created warm layer. This can be done, for example, by spiked rollers.
  • the holes can also be vibrated using suitable devices. If the holes are made in the hot mix, this can also cause the bituminous mix to be compacted at the same time.
  • FIG. 1 shows a conventional layer 1 made from a mixture of bitumen or tar with minerals, into which recesses 2 have been pressed or vibrated in the warm state and which are poured out with a stiffening material 3.
  • Layer 1 could also consist of a layer that has already been created and is to be subsequently braced. In this case, the recesses 2 would have been made through bores or with pneumatic hammers.
  • a bituminous layer 4 of conventional design is then applied to the layer 1 provided with the stiffening plugs or pins 3.
  • the stiffening plugs or pins 3 can be arranged in any pattern over the layers to be stiffened.
