Definitions

  • the invention relates to a method for producing structured and / or having a color effect, bituminous coverings for road and path construction.
  • bituminous coverings obtained using the new process are equally suitable for parking lots, airfield take-off runways, playgrounds, sidewalks, low-traffic zones, shopping and shopping streets, industrial floors, screed materials and other surfaces made of bituminous material.
  • bituminous cover layers i.e. Mineral topping mixtures produced with bitumen as a binder, such as mastic asphalt, asphalt concrete, grit mastic coverings, asphalt mastic, surface protection layers, asphalt mixing macadam etc. are subject to the natural barrier that is given by the black-brown intrinsic color of the bitumen.
  • a temporary brightening and a gray to medium gray top layer can be obtained.
  • This brightening - not coloring and structuring - can only be preserved for longer periods if - as stated at the beginning - heavy traffic removes the surface bitumen film and the brightness of the mineral material is revealed.
  • Minerals that are used for this suitable ie can be rated as "light” or colored in the above sense, are gabbro, granite, limestone, moraine rock, quartz, porphyry, trachite, labradorite, etc.
  • bituminous coverings from standard mix (mastic asphalt, asphalt concrete, etc.) with colored synthetic resins, i.e. Spray asphalt already laid with mixtures of pigments and synthetic resins (pigment embedding in synthetic resins) or treat them in any other way.
  • this method gives the surface an "artificial" appearance and obviously represents the traffic-related nature of the road ( Grip and roughness) in question.
  • the known properties of a real bituminous road surface are no longer given.
  • the object of the invention is to remedy the disadvantages of previous methods of lightening or coloring and structuring bituminous surface coverings and to create a method which indicates a path that is targeted to a permanent, variable from the influence of traffic, depending on the area of application Staining and / or structuring of bituminous coverings leads, whereby a variety of structures and colors of the coverings can be achieved.
  • the combination of a special mix structure and HWSB according to the invention removes a certain, controllable layer of the mortar and the binding agent.
  • the pure mineral grain or the so-called core asphalt is exposed.
  • This now has both its own structure and its own color and provides a (new) surface layer with thicknesses between approx. 2 and approx. 10 mm surface roughness, which remains firmly anchored in the mix in the lower area via binders and mortar.
  • the mix suitable for the method according to the invention is bound to a certain extent to a certain amount of coarse grain, so that only the mortar or binder, but not the grit material itself, is carried away at the HWSB.
  • the intensity of the HWSB is to be coordinated with the chosen covering structure.
  • the HWSB takes place at room or ambient temperature after the mixture has cooled with a high-pressure water jet at over 300 bar jet pressure, a water volume of approx. 2 to 25 1 / m 2 area and a duration of at least 60 sec / m 2 . It goes without saying that these details (pressure, amount of water, time per m 2 ) are variable and can complement one another.
  • the composition of the mix, the time after compaction of the same and the desired depth of removal play a role, although it is no problem for the person skilled in the art to determine these variables in a short experiment and adapt them to the given possibilities.
  • HWSB high-pressure water jet generators
  • the temperature of the water jet can be above ambient temperature, for example up to 100 ° C. and above, which means that it is also more saturated Water vapor can be beneficial.
  • Devices suitable for this are also available industrially and are not the subject of the invention. Mortar removal using sandblasting might also be possible, but here the stone grain is inevitably damaged and partially removed.
  • the effective limit values of water pressure, water temperature, duration of the jet treatment, amount of water etc. are a function of both the desired removal depth and the mix build-up. It is of crucial importance, however, that the depth of the removal does not exceed a value of approx. 60% of the maximum grain size in the top layer, so that the remaining 40% of the coarse grain is firmly anchored in the material that has not been removed.
  • Figure 1 shows in a representation not to scale the structure of a mastic asphalt covering consisting of grit (2) and mortar (1), which rests on the substructure (3).
  • a mastic asphalt covering consisting of grit (2) and mortar (1), which rests on the substructure (3).
  • it has the following composition:
  • the mastic asphalt laid at a temperature of approx. 200 - 260 'C is treated after cooling with a high pressure water jet at ambient temperature under a jet pressure of over 400 bar until a split layer of approx. 10 mm depth, d.s. about 60% of the diameter of the quartzite chips 11/16 is exposed. This corresponds to dimension (a) in Figure 2, based on the largest diameter (b) of the maximum grain.
  • a mortar and binder-free layer (4) is created, the cavities of which make the bare, colored grain (2) visible. This grain (2) remains embedded in the lower area in the mortar (1) and is firmly anchored in it.
  • the mineral grain (grit) with the largest diameter can be present in broken state without regular habit, i.e. as actual grit, but it can also be used as a sieve fraction of a gravel material, i.e. as round or oval grain.
  • the proportion of the chippings or pebbles with the largest grain diameter in the mix should be between approximately 15 and 50 parts by weight, in particular between approximately 20 and 40 parts by weight and preferably between approximately 25 and 30 parts by weight.
  • a split structure of, for example has a grain size of 0/16 mm proven to be particularly advantageous (bitumen content approx. 7% by weight).
  • the maximum grain size of 8/11 or 11/16 mm is therefore approximately 18 - 31 parts by weight.
  • Rolled asphalt generally requires the same grain size range when using porphyry grit.
  • a split structure of, for example,
  • the removal depth by HWSB is approx. 7 mm, corresponding to a maximum value of approx. 60% of the maximum grain size.
  • the new process exposes the coarse grain in its specific surface properties (color, gloss, structure, etc.).
  • the surface of the covering also takes on these properties as a whole. It is understood that a variety of color effects and structures on the surface of a road surface, etc. can be achieved by a suitable choice of the coarse grain.
  • suitable pigments such as titanium dioxide, aluminum oxide (white pigments), iron oxide red, chromium oxide red and yellow, spinels, mixed oxides of heavy and non-ferrous metals, slags etc., but especially also the large number of Colored pigments of silicate, aluminate, The chromate and antimonate series can be used directly as "grit".
  • the abrasion resistance permits the use of such pigments only for surfaces which are not subject to high stress.
  • artificial chippings e.g. LUXOVIT (R)
  • round grains made of similar materials can also be used.
  • Such a film (5) partially covers the binder-free volume (4) between the exposed grain (2) and not only prevents acidic water from penetrating the floor covering, but can also be used as a clear film, e.g. formed from acrylate or methacrylate or similar clear polymers, the color of the grain (2) and its structure preserved unchanged for a long time.
  • a clear film e.g. formed from acrylate or methacrylate or similar clear polymers, the color of the grain (2) and its structure preserved unchanged for a long time.
  • suitable, possibly also pigmented, but generally clear synthetic resins and polymers (6) as shown in FIG. 3 / b.
  • Refinement of the exposed surface according to FIG. 3 / a or 3 / b is particularly advantageous if, in the case of relatively low traffic volume, a colored and / or structured surface that is particularly effective for the eye is to be created, as is the case with parking lots, play and sports facilities, etc ., Sidewalks, terraces, swimming pools etc. the case is.
  • mixed grit coarse material such as slate chippings, porphyry grit and pebbles, i.e. mixtures of mainly broken and round-oval material, the structural effect can be increased even further. It is also possible to grind off the rock peaks remaining after filling up the "valleys".
