Definitions

  • This patent concerns the sector of road signs and road safety devices, and in particular it concerns road markings.
  • paint has the drawback that it fades very quickly, due to the passage of vehicles. Furthermore, paint has scarce reflecting properties and therefore in case of insufficient light or fog the road markings are not clearly visible.
  • the object of this patent is constituted by a new process for carrying out modular refracting elements to be inserted in the road surface and by the modular refracting element obtained therefrom.
  • the aim of the new modular element to be inserted in the road surface is to reflect the light projected by the lamps of the vehicles in transit.
  • Another aim of the new modular element is to reflect light even after being subjected to intense wear.
  • a further aim of the new modular refracting element is to be raised from the road surface and to produce sound waves that can be sensed by the drivers.
  • the new modular refracting element is carried out by introducing into apposite moulds a quantity of cement mix slightly smaller than the quantity needed to fill the mould completely.
  • the layer comprising binder, aggregate and microspheres is laid on the upper surface of the element and then compressed.
  • Figure 1 is an axonometric view of the new modular element (M).
  • the new modular element (M) comprises a body (M1) to which a layer of refracting mix (M2) is applied.
  • the body (M1) is preferably parallelepiped-shaped, or can be carried out in any other suitable geometric shape.
  • Said body (M1) is preferably made of cement mix and is suitable for being applied and fixed to the road surface or to the road sub-base.
  • the reflecting layer (M2) is constituted by a mix of microspheres, binder and aggregate.
  • the microspheres have indicatively very small diametre, of the order of millimetres, and are constituted by glass, pure glass, semi-pure glass or are ceramic coated.
  • the binder can be constituted by cement, chemical bonding agent, or another type of binder suitable for binding the microspheres to one another and to the body (M1).
  • the reflecting layer (M2) is applied to the upper part of the body (M1) and its upper edges are preferably inclined, radiused or rounded.
  • the new modular refracting element (M) constituted as described above offers considerable advantages.
  • the new modular refracting element (M) can be inserted both in the already made-up road surface and in the road sub-base, on which the road surface must be laid.
  • the new modular refracting element (M) does not lose its reflecting characteristics over time, since it doesn't wear out due to the passage of vehicles, or only its upper layer wears out, showing the underlying reflecting part.
  • the new modular refracting element (M) is much more luminous, both in good and in bad visibility and light conditions.
  • the new modular refracting element (M) can be used to carry out any type of road markings, for example road center or road side lines, as shown in Figure 2, since the shape of the reflecting layer (M2) with inclined or rounded edges constitutes a raised section producing sound waves that can be sensed by the drivers.
  • the new refracting element (M) constituted as described above is carried out according to the process described below and represented diagrammatically in Figures 3a, 3b, 3c, 3d, 3e.
  • the cement mix that makes up the body (M1) is poured into apposite moulds (S1), preferably multiple moulds, in a slightly smaller quantity than that needed to fill each mould completely ( Figure 3a).
  • Said cement mix is vibrated and compressed by relevant counter-moulds (S2), in such a way as to give it the shape of a parallelepiped or in any case to obtain a flat upper surface ( Figure 3b).
  • microspheres are spread, strewn or laid onto said refracting mix (M2), after properly compacting it through vibration (Figure 3d).
  • the production process of the new modular refracting element (M) as described above may include only the spreading, strewing, or laying of microspheres on the cement mix already introduced in the mould (S1) and compacted.
  • the production process of the new modular refracting element (M) as described above may include the introduction of the refracting mix (M2) only into the mould (S), without the successive spreading, strewing or laying of microspheres.
