Definitions

  • the invention relates to a protective layer for the surface of traffic areas according to the preamble of claim 1 and a method for applying a protective layer.
  • Another fine-grain additive which can be used as a filler is known from EP 0 153 269 B1 and is obtained as a fine-grain mixture by dry grinding a mineral-hydrophilic component and at least one hydrophobic water-insoluble component.
  • This agent is also intended for road construction of bituminous cover layers and is intended to inhibit ice formation due to its salinity.
  • DE-P 42 30 545.4 which is not prepublished, proposes a further process for the production of salty crushed sand or grit, which in turn is used as a road construction additive with the aim of inhibiting ice formation.
  • This agent should have an improved stability behavior of the individual grain.
  • additives that inhibit ice formation are only introduced into the entire surface layer of traffic areas. This means that, for example, road surfaces are only given anti-icing properties if either a new road is built or an existing one is completely renovated by removing and replacing the previous surface course. Otherwise, if necessary, you have to rely on the usual application of road salt, because an early thorough renovation of an existing road is generally out of the question for cost reasons. Since aggregates that inhibit ice formation are significantly more expensive than conventional road building materials, it must be regarded as disadvantageous that the majority of the ice-inhibiting substances introduced remain firmly enclosed in the interior of the top layer and thus can never develop their intended effect, since the Top layer must be replaced long before it is completely worn out across the area. Only a small part of these additives is exposed through normal wear of the cover layer over time and can act as intended.
  • the object of the invention is to propose a way that makes it possible to provide surfaces of already existing traffic areas with comparatively little effort permanently with an anti-icing effect. Seen over the service life of the top layer, a larger part of the total substances used to inhibit ice formation should be effective than so far.
  • a cover layer is usually of the order of about 3 to 6 cm (the smallest permissible installation thickness of a cover layer is at least 2 to 3 cm according to the German regulations ZTV bit-StB 84, 1984 version), the layer thickness of a surface protection layer is significantly smaller and lies in the range of 0.5 to a maximum of 1.5 cm.
  • Surface protection layers are applied in accordance with ZTV bit-StB 84 as single-layer or two-layer surface treatments or as sludge on a suitable surface.
  • protective layers can neither level the flatness nor the load-bearing capacity of the reversed pool.
  • the material for a cover layer is mixed thoroughly in the mixing unit, the creation of a surface protective layer involves the application of a material mixture which is produced "in situ" at the place of installation.
  • the active ingredients which inhibit ice formation are no longer used exclusively in the construction of cover layers, but instead e.g. to be used as a protective layer of traffic surfaces within the scope of a surface treatment, i.e. to be installed specifically in the volume area in which the effect of ice formation inhibition is to be achieved, i.e. in the surface or in the area near the surface, which can still be exposed by the usual wear and tear. Since the surface treatment always involves the application of comparatively thin layers, there are particular advantages when the treatment is in the form of
  • Binder is applied with subsequent splitting, and at least a large part of the active ingredients are contained in splitting particles. Since the individual grit clearly protrudes from the binder due to its size, a much larger part of its surface is freely accessible and therefore effective, as can be the case with a grit embedded in the top layer, of which Only the surface areas above can usually be effective.
  • the invention provides for the mineral component, which is usually used in such surface protection layers, to be replaced in whole or in part by a granular mineral material which contains an active ingredient with which the formation of ice is inhibited.
  • the active substances are preferably NaCl, KCl and MgCL individually or together.
  • the proportion of the material containing the active ingredient in the total mineral component should be at least 10% by weight, preferably at least 30% by weight, in order to ensure a good effect.
  • the material containing the active ingredient can be added in the form of filler and / or crushed sand and / or grit.
  • the addition as chippings is particularly preferred, the proportion of the chippings in the mineral component should preferably be in the range of 20-30% by weight.
  • a plastic resin such as epoxy resin can be used as a binder in the surface treatment.
  • bitumen-based binders in particular in the form of bitumen emulsions, which are intended for cold installation, are particularly preferred. Pure bitumen is expediently used as a binder for hot installation.
  • the use of the coating composition according to the invention as ready-mixed sludge is expedient, the active ingredient being introduced in the form of saline filler and in particular saline crushed sand.
  • a surface treatment with grit was carried out on an existing asphalt concrete surface.
  • a bituminous was used as the binder unstable cationic emulsion with 70% bitumen used.
  • Finely chippings sprinkled evenly, rolled in with a static roller and then treated with a rubber wheel wiper.
  • 30% by weight of fine chippings consisted of a broken mineral consisting essentially of MgO and MgCl.
  • the new surface created in this way showed good grip both in summer and in winter.
  • the top layer showed a very good brightening and had an improved drainage ability.
  • Under winter conditions a clear reduction in ice and frost formation was found. After heavy snowfall, the clearing capacity was excellent because the snow had no firm adhesion to the ground.
  • braking distances for road vehicles were significantly shorter.
  • a cement concrete pavement of a street was treated in the same manner as in the previous example. The effects described above also occurred here. The adhesion of the coating compound to the substrate was absolutely good.
  • a thin protective layer was applied to the asphalt concrete ceiling using the cold paving (slurry construction method). 5 kg of a slurry was applied per square meter of surface, which consisted of 12% by weight of a binder in the form of an unstable cationic emulsion containing 60% bitumen. The remaining 88% by weight was made up of crushed sand 0/3. This crushing sand consisted of one third of morane crushing sand and two thirds of one consisting essentially of MgO and MgCl broken mineral. After treating the surface, it had similar properties to the top layer in the two previous examples.

Abstract

Un matériau d'enduction pour le traitement en surface de couches de revêtement de surfaces de circulation comprend un mélange d'un liant et d'un composant minéral granulé. Afin de conférer à peu de frais un effet anti-verglas permanent à des surfaces de circulation déjà existantes, le composant minéral est constitué au moins en partie d'un matériau contenant une substance active anti-verglas.
