Definitions

  • the invention relates to an asphalt for floor coverings with an at least partially binder-free surface, the minerals with fractions of grain sizes> 2 mm (grit and / or gravel), with fractions of grain sizes between 0.09 mm and 2 mm (sand) and with fractions of grain sizes ⁇ 0.09 mm (filler) and binder.
  • the invention further relates to a method for producing asphalt for floor coverings with an at least partially binder-free surface, and to an asphalt produced by this method.
  • Such asphalts for floor coverings are known in the prior art. They were used for the first time at the 1972 Olympic Games in Kunststoff and are available under the name "Olympiamastix".
  • Such a binder-free surface allows the asphalt to be colored, which is determined by the mix and not by the binder, which usually contains bitumen and is therefore black.
  • such asphalts can also be used where such coloring is particularly important for traffic-related or aesthetic reasons. Binder-free surfaces are also used because brake marks from bicycles and other vehicles cause little or no surface discoloration, since the rubber abrasion adheres poorly or not at all to the binder-free surface.
  • asphaltenes according to the prior art require a high concentration of binder in the layer below the surface, which in turn precludes water permeability.
  • the sharp-edged surface of the mastic asphalt forms the surface of the known asphalt, which increases the risk of injury for falling pedestrians and cyclists, among other things.
  • the larger parts of the material to be mixed namely the large-volume portions with a diameter of more than 5 mm, are brought to the surface in a separate operation when laid on a surface.
  • the remaining asphalt is spread at high temperature, ie at temperatures up to 240 ° C, at which the mastic asphalt is sufficiently flowable and therefore processable, and the large-volume portions are applied to the surface immediately afterwards.
  • the large-volume fractions Due to the sufficient viscosity of the mastic asphalt at these temperatures, the large-volume fractions partially sink so that on the one hand they come into contact with the binder on the lower side and therefore adhere, and on the other hand the upper side of these large-volume fractions remains free of binder.
  • a disadvantage of this laying method is that the large volume portion of the subsequently applied mineral mixture is not mechanically stable, since the large volume portions of the mineral mixture have a poor connection to the binder in the mastic asphalt and can therefore be easily removed mechanically. In use, this easily leads to bare spots on the surface, so-called bald spots, on which no binder-free stones can be seen.
  • this asphalt is also very sensitive to contamination of the large-volume portions of the mineral mixture, as this can again significantly reduce the adhesion to the binder.
  • the asphalt applied in this way is not water-permeable due to the system, because the poured asphalt must be sufficiently flowable and, above all, sufficiently dense to be able to incorporate the large-volume mineral components sufficiently firmly.
  • the invention is therefore based on the object of providing an asphalt with a partially binder-free surface which has a slightly rough surface structure and, in a particular embodiment, avoids the disadvantage of surface sealing.
  • Another object of the invention is to provide a drive to spread asphalt with a partially binder-free surface available, which avoids the above-mentioned disadvantages of poor integration of the large volume mineral parts of the surface on the binder and the complicated laying method.
  • an asphalt according to the preamble of claim 1 in which the mineral mixture contains 80 to 90% by mass of particles with grain sizes> 2 mm (grit or gravel), 6 to 16% by mass of parts with grain sizes between 0.09 mm and 2 mm (sand) and 4 to 6% by mass of grain sizes ⁇ 0.09 mm (filler) and in which the proportion of Rundkom (gravel) in the minerals with grain sizes> 2 mm is greater than 80 mass%.
  • this asphalt is permeable to water.
  • Rundkom which is sufficiently stably connected to the binder in the asphalt according to the invention, the point of view of reducing the risk of injury to pedestrians, in particular children playing and / or cyclists after a fall on the asphalt according to the invention is of importance since the The proportion of sharp-edged minerals on the surface is very low.
  • the asphalt according to the invention particularly preferably has a mineral mixture of 83 to 87% by mass of grit or gravel, 7 to 13% by mass of sand and 4 to 5.5% by mass of filler.
  • the asphalt according to the invention has particularly favorable properties if it has a mineral mixture with less than 10% by mass of grit with grain sizes of more than 8 mm and at least one of the following components in the stated weight:
  • Grain size between 8.0 mm and 11.2 mm 8.0 M .-% to 9.8 M .-%
  • Grain size between 0.71 mm and 2.0 mm 5.0% by mass to 6.0% by mass
  • Grain size between 0.25 mm and 0.71 mm 2.8% by mass to 3.6% by mass
  • Grain size between 0.09 mm and 0.25 mm 1.2% by mass to 1.8% by mass
  • Grain size smaller than 0.09 mm 4.2 mass% to 5.2 mass%
  • the mineral mixture with grain sizes between 0.09 mm and 2 mm contains crushed sand, preferably fine crushed sand. It can also be advantageous if the minerals contained in the asphalt contain at least partially light materials - natural or artificially produced. This can be helpful if the filler contains limestone flour.
  • the binder content of the asphalt according to the invention is advantageously between 4.5 and 6.0 mass%, preferably between 4.8 and 5.6 mass%.
  • the binder contains colorless material. It is particularly favorable if the binder is polymer-modified, which improves the long-term stability against weather influences.
  • the stabilization of the binder is also increased if fibrous materials are added to it, the proportion of which is preferably less than 2% by mass, particularly preferably by 0.4% by mass, of the total weight.
  • the asphalt according to the invention can also be made permeable to water, which is of particular advantage.
  • the void content is greater than 8 vol.%, A void content in a range between 12 vol.% And 18 vol.% Is particularly advantageous.
  • the water-permeable asphalt according to the invention is particularly advantageous, since the natural mineral surface makes it easier to clean the asphalt, and soiling can therefore not penetrate the pores so easily.
  • the object is achieved by the provision of a method for producing an asphalt according to the preamble of claim 14, according to which the asphalt mixture is first applied to the surface to be asphalted in one operation and the surface is then, preferably after curing, at least partially from the binder is liberated.
  • the process according to the invention for producing asphalt for floor coverings with an at least partially binder-free surface from asphalt mixture, containing minerals with proportions of grain sizes> 2 mm (grit and / or gravel), with proportions of grain sizes between 0.09 mm and 2 mm (sand ) and with proportions of grain sizes ⁇ 0.09 mm (filler) and binder, is carried out by first applying the asphalt mixture to the surface.
  • the surface is then treated — preferably mechanically — in order to partially detach the binder from the surface.
  • Particularly good results are achieved with sandblasting after the asphalt mixture has hardened, but it is also possible to detach binders on a chemical basis using solvents.
  • the method according to the invention can be used both for water-permeable and for water-impermeable asphalts, but in particular also for the production of all asphalts described above and claimed with claims 1 to 13.
  • FIG. 1 shows a cross section through an asphalt layer according to the invention
  • Figure 2 the screen line of a mineral mixture for use in the asphalt according to the invention.
  • Figure 1 shows - not to scale - an asphalt layer 1 according to the invention, which is on a conventional substrate (base layer) 2, which is not described in more detail here.
  • the different sized grains of the mineral mixture can be seen, namely the gravel 3 and the sand 4, the very small-grain filler 5 is no longer shown.
  • the grains are surrounded by binder 6, the fibrous materials 7 no longer being recognizable in the binder. If the mineral mixture is selected appropriately, cavities 8 and thus channels are created between the grains through which the water can flow from the surface through the asphalt. No binder can be seen on the surface itself, i.e. the grains 9 of the mineral mixture forming the upper end are natural and therefore ensure the color impression of the asphalt.
  • the screening line 21 of a particularly suitable mineral mixture is shown in FIG. 2.
  • This mineral mixture consists of approximately 85 mass% of light grit or gravel 2/8 mm (Rundkom), of dolomite fine crushed sand 0/2 mm and limestone powder as filler, the Sand and limestone flour components also support brightness.
  • the density of the asphalt in this mixture is approximately 2.15 g / cm, a compaction temperature of 135 ° C being sufficient for the asphalt.
  • a void content between 13.3 and 18.0% by volume was thus achieved. Although this void content is consistently below the value of greater than 18.0 vol.% Provided for water-permeable asphalt in the prior art, a high water permeability is achieved with the asphalt described.
  • this asphalt mixture After being applied to the base course, this asphalt mixture still has binders on the surface. This can be removed from the surface at any time after the asphalt mixture has cooled sufficiently. the. Sandblasting of the surface has proven itself in the first attempts. This also ensures that the asphalt according to the invention can be laid as usual, since there are no special problems. Special knowledge and special caution are not required for this.
  • the new process allows, among other things, that asphalt with a mixed material temperature between only 140 ° C and 160 ° C can be used.
  • the emission values reduced by the lower temperatures, which are mainly caused by outgassing, are of particular advantage, which also relieves the environment.
