Definitions

  • the invention relates to a surfacing for a pavement, for example for a square, roads and paths, where, in addition to the functional requirements, aesthetic requirements can also be met.
  • Rolled asphalt is easy and quick to lay for large surface areas.
  • the appearance is uniform black to grey without the addition of colouring pigments.
  • This type of surfacing is not found to be aesthetically pleasing. By changing the appearance a more decorative and aesthetic appearance is obtained.
  • the invention comprises the production of a hardened surfacing in accordance with the following steps:
  • the result of this method can reveal a surfacing which displays cut granules and particles of different shape and colour embedded in, for example, a black matrix. This gives a special aesthetic appearance.
  • the substrate Before the direct laying of the surfacing, the substrate is a foundation of, for example, sand or crushed rock or a combination of the two. This substrate could also be a cement-based concrete.
  • the substrate is then a non-sticky surface, such as an area comprising a layer of sand, horizontally levelled and compacted, which can be re-used.
  • these elements are made of compacted dense rolled asphalt or compacted open-textured rolled asphalt with a percentage voids of less than 20 % (V/V), which are laid as a continuous layer.
  • V/V percentage voids of less than 20 %
  • Elements can also be made in another way. Moulds of identical dimensions are arranged on a non-sticky layer, such as a compacted sand layer, a metal plate or wooden slab, which has been treated with a release agent. These moulds can, for example, consist merely of a future outer edge. At least one steel strip that extends all round is accommodated in this outer edge. These moulds are then filled with hot rolled asphalt (bitumen as binder) or "C-Fix®" asphalt (residue from oil refining as binder) to well above the top of the outer edge of the mould. The height of the overfill must correspond to the settlement after compaction of the layer plus the height of the top portion to be removed.
  • a non-sticky layer such as a compacted sand layer, a metal plate or wooden slab, which has been treated with a release agent.
  • These moulds can, for example, consist merely of a future outer edge. At least one steel strip that extends all round is accommodated in this outer
  • the layer In the hot state the layer is compacted using, for example, a roller. After cooling of the layer, a top portion of the layer, such as a thin layer, is removed down to the top of the outer edge of the moulds. Numerous cut surfaces of granules and particles will now have appeared at the surface. The outer edges of the moulds that are in contact with one another stick only to the asphalt and not to one another. Elements have then been produced that can be released from the non-sticky substrate. The elements can be transported, for example after storage, to another location for use as surfacing for a pavement, a floor or the like.
  • the upper layer In order to obtain a desired appearance, for example a specific colour or effect, it is possible to use in the upper layer at least granules that, for example, have originated from old or existing river beds via extraction or have been obtained from igneous or sedimentary rocks via crushing. This usually refers to gravel, the particle size of which is between 2 and 63 mm.
  • granules of rock-like material that have a particle size of between 1 and 80 mm.
  • An alternative is to make the particle size between 3 and 40 mm.
  • a binder that has been obtained from oil refining such as modified bitumen or a residue material with the trade name C-Fix®, is preferably used for binding the granules.
  • Known plastics can be added to this binder to improve the binding properties.
  • Fillers or sand can also be added to the binder in order to obtain a sufficiently dense surfacing, the percentage voids in the compacted layer being less than 7 %.
  • the type of bitumen it is possible to use either the most common "black" bitumen or white bitumen, which is termed colourless. It is also possible to add colourants to the binder to colour the matrix of the top layer.
  • particles of a specific shape are distributed in the asphalt mixture before the top layer is laid. This can be done by adding the particles at the asphalt production facility or on site, where the rolled asphalt has to be laid, after which the particles are mixed into the mixture such that they are well distributed through the mixture. Distributed means that the particles are mainly separated from each other. The particles are decorative elements and to date have never been used in this application. When the layer is compacted these particles are also compacted.
  • the dimensions of the particles are preferably on the whole between 2 and 100 mm. As an alternative, said dimensions can be between 2 and 60 mm. These particles can be metal, ceramic, glass, wood, plastic or hard decorative stone particles.
  • decorative stones are that type of stones that have not been used in rolled asphalt to date.
  • the metal particles used are preferably metals which do not have the propensity to acquire an oxide coating or acquire only a very thin oxide coating.
  • One example is stainless steel. Using, for example, particles of high-grade stainless steel, black bitumen and the correct types of gravel it is possible to simulate the appearance of rare black marble.
  • These particles can, for example, approximate to a block, a cube, a pyramid or a sphere. These particles could also be somewhat plate-shaped. The particles could also be in the shape of a symbol or image or of a trade mark, such as a bicycle, telephone, coin, flower, municipal coat of arms or a company trade mark. Another possibility is that reflective and/or photoluminescent material is mixed into the particles of fusible, transparent substances, such as glass and plastic. In the presence of little or no light these particles can, for example, reflect light or light up in the dark. Squares and shopping streets that light up could, for example, in this way give a distinctive appearance in the dark.
  • the removal of a thin layer from the top layer, so that a smooth top with a structure of cut granules is produced, is preferably obtained by means of milling and/or grinding. Fine grinding, i.e. polishing, will have to be carried out as the final treatment in order to make the top shine or glisten.
  • the surface is preferably provided with a transparent coating for protection and/or to improve the slip-resistance of the top surface.
  • the invention also comprises a surfacing which can be used for a pavement or a floor, which has been produced in accordance with what has been described above.
  • This surfacing can consist either of a continuous layer or of tiles. In the case of a continuous layer it is possible to give this the appearance of a covering made of tiles by making shallow saw cuts in the form of a tile pattern. In the case of separate tiles these can have the dimensions of block paving, pavement slabs or decorative tiles and also of slabs, which can have large to very large dimensions, for example 1 m x 2 m to 3 m x 8 m.
  • Figure 1 shows the layer 1, which is laid hot and compacted, on a substrate 2.
  • This substrate can, for example, be of sand, crushed rock or layers of rolled asphalt or "C-Fix®" asphalt or of cement-based concrete laid beforehand.
  • Figure 2 shows the top layer from Figure 1, where a thin layer or the top portion 3 has been removed from the top and a machined surface 4 has been produced. Top portion 3 has been removed, for example, by a mechanical treatment such as milling or grinding, optionally followed by polishing.
  • Figure 3 shows part of the surface 4 which is a consequence of the removal of the top portion 3.
  • Many granules 4 show a cut surface, which granules are embedded in a matrix 7.
  • the matrix can consist of a fusible binder, obtained from oil refining, which is optionally mixed with known plastics, fillers or sand. Colouring pigments can optionally have been added. A few particles 6 can be seen at the surface 4.
  • Figure 4 shows only a cross-section of the machined layer 1 with particles 6 therein distributed through the layer 1, in accordance with the invention.
  • the particles 6 have, as a result of mixing into the asphalt mixture before laying layer 1, laying layer 1 and then compacting, acquired a position that cannot be determined in advance.
  • the cut surface of these particles can have various shapes.
  • the cut surface can have a triangular or rectangular shape. Block-shaped or cube-shaped particles have been used in Figure 4 as an example.
