Definitions

  • the invention relates to a road surface for drivable traffic areas, primarily in the area of filling stations for fuels, petrol stations or the like, from a road surface resting on a frost-proof substructure made of prefabricated individual components laid separately from one another, such as e.g. Paving stones made of natural or artificial materials.
  • pavement coverings from prefabricated individual components such as from paving stones made of natural or artificial materials. Since a pavement made of paving stones makes it easier to adjust irregular floor plans, but also different heights, than a continuous, closed pavement, pavings are usually used for traffic areas that cannot be used to manufacture pavers, i.e. for smaller, even angled areas, e.g. Courtyards, petrol station entrances or the like.
  • Road pavements made of paving stones are usually laid on a substructure made of a material that is frost-proof and able to distribute the loads resulting from the traffic load.
  • a substructure made of a material that is frost-proof and able to distribute the loads resulting from the traffic load.
  • paving has the property of allowing rainwater to drain directly into the subsoil, which makes it particularly valuable from an environmental point of view.
  • this also results in the risk of contamination of the soil by liquid or solid pollutants that can be flushed into the ground with the water.
  • paving requires a layer of a material that is non-cohesive and therefore peelable to a flat surface; this underlay usually consists of sand and is therefore permeable to water.
  • this layer of sand it would be possible to apply this layer of sand to a sealing layer, for example made from a plastic film or from clay minerals.
  • seals made of plastic films are not resistant to hydrocarbons and conventional seals made of mineral sealing materials are not sufficiently load-bearing and are also not frost-proof
  • the arrangement of a sand layer above a sealing layer has the additional disadvantage that hydrocarbon oozing through the joints of the paving spread horizontally in the sand layer and then through diffusion or even through cracks in the sealing layer can also find a way into the underground.
  • the invention has for its object to provide a secure seal for road surfaces from prefabricated individual components, e.g. To create paving stones that are not only stable and frost-proof, but also resistant to hydrocarbons and durable.
  • the invention is based on the knowledge that a mixture of gravel and sand with high-quality clay minerals, e.g. Montmorillonite, the existing sealing layer is frost-proof on the one hand because the individual components of the mixture do not cause frost elevations, i.e. they can also be installed within the frost depth, but on the other hand they are sufficiently load-bearing due to the coarse grain structure.
  • high-quality clay minerals e.g. Montmorillonite
  • the installation of the material forming the sealing layer in dry, i.e. pre-dried state has the effect that, as with sand, a flat surface suitable for placing the individual components can be created by pulling off with the usual tools.
  • the dry material is compacted while filling the pore spaces. Since the volume of the fine grain fraction of the mixture is greater than the pore volume of the coarse grain fraction, fine material remains after the pore spaces of the coarser material are filled, which rises to the surface and from below into the joint spaces between the individual components and fills them up solely due to the vibrating energy .
  • the methods of installation and compaction can be coordinated and the grain size graded so that the coarse grains are surrounded by the fine grains. This results in a very small pore space of 25 to 20%, which is additionally sealed when moisture is added by the swelling of the montmorillonite.
  • a sealing layer assembled and installed according to the invention has the necessary load-bearing capacity even for heavy traffic.
  • frost the pore water remains finely distributed in the mixture; there is no water absorption from the outside, i.e. there is no increase in the water content or enlargement of the pore space. Ice lenses and thus uplifts do not occur.
  • 1 denotes a conventional base layer, which is usually e.g. a thickness of approx. 15 cm and has the task of frost-proof foundation and transmission of the loads resulting from the traffic loads to the ground.
  • a frost protection layer (not shown); below the upcoming floor.
  • a sealing layer 2 on which the actual road surface 3 is then made up of individual components, here made of concrete paving stones 4, e.g. Compound paving stones.
  • the sealing layer 2 expediently consists of a mixture of approx. 65% grown gravel with a grain size of 8 to 16 mm, approx. 25% sand with a grain size of 0.1 to 0.8 mm and approx. 10% bentonite.
  • the materials for this mixture are dry, i.e. pre-dried, non-cohesive state mixed and installed in this state.
  • the dry installed mixture not only forms the seal immediately below the road surface 3 and in the area of the joints 6, but also due to its composition from a coarse grain structure, fine particles and clay minerals
  • the load-bearing sealing layer 2 is shown in FIG 2 shows an embodiment in which a mixed-floor seal 7, which is assembled and installed in the usual way, for example, is arranged on the base layer 1.
  • the correspondingly thinner sealing layer 2 'according to the invention arranged thereon consists here only of fine fractions, for example about 70% of sand with grain sizes 0.1 to 2 mm and about 30% of clay minerals, for example montmorillonite.
  • This mixture is installed and removed in a dry state, that is to say without cohesion, and compacted by paving stones 4 after the pavement 3 has been laid on, from paving stones 4.
  • the vibrating energy entered in this way not only causes the particles of the clay mineral fraction in a particle size of 1 to 2 my into the pore spaces penetrate the sand portion, which has a particle size of about 100 my up to 1 to 2 mm; since here too the volume fraction of clay mineral is larger than the pore space of the sand fraction, the portions of the clay mineral that are no longer required to fill the pore spaces enter upwards and penetrate into the joints 6 between the individual paving stones 4 from below.
  • the sealing layer 2 'immediately below the paving stones 4 reaches a thickness of about 2 cm in the final state.
