Definitions

  • the invention relates to a method for producing mastic asphalt coverings according to the preamble of claim 1.
  • Mastic asphalt usually has a more or less dark gray surface and is usually lightened somewhat by increasing the amount of chippings in the surface area. It is also known to produce continuously colored mastic asphalt coverings, with some of the minerals being replaced by a pigment. However, this can only be carried out to a very limited extent because a relatively high pigment content is required to cover the black bitumen paint, which increases the costs, and because the color pigments in question often do not meet the requirements that are met by chippings or a mineral structure of mastic asphalt will. Another disadvantage is that the abrasion of such a colored mastic asphalt - possibly pasted by wetness - adheres to shoes and is then introduced into houses and the like. All these disadvantages are responsible for the fact that this method has not found its way into practice.
  • German patent application Z 4266 V / 37 d to which the claim relates with its preamble.
  • This process involves pouring mastic asphalt into a hot mass broken asphalt grains of about the same melting point as the mastic asphalt mass, but of different color, tapped in and spread after softening in the hot mastic asphalt mass.
  • DE-A 1 943 935 describes a process for improving the initial roughness of mastic asphalt surfaces, in which grit is sprinkled on the still hot mastic asphalt surface immediately behind a screed used for smoothing, which due to its own weight spreads into the still highly plastic mass of the surface partially impresses.
  • the invention has for its object to provide a method with which it is possible at low cost to produce surface-colored mastic asphalt coverings that are characterized by abrasion resistance even with heavy and even punctiform loads.
  • film chips made of plastic are applied to the still hot, fresh surface of the smoothly poured mastic asphalt. You can achieve all the desired variations in terms of color and / or size of the film chips.
  • the film chips can consist of any plastic; Polyvinyl acetate and copolymers of vinyl acetate and acrylate but also polyacrylate and polyethylenes and polypropylenes are particularly suitable. Foil chips based on polyvinyl acetates are preferred for indoor applications, while foil chips made of polyacrylates are preferred for outdoor applications.
  • the length of the shredded film can be chosen according to your preference and area of application. It is generally between 2 and 12 mm, and one or more fractions can be used.
  • the film thickness of the film chips should be sufficient to ensure safe handling.
  • the film chips can be produced in the usual way as plastic films, which are then cut accordingly. Waste material from the plastics industry, in particular the packaging industry, or from producers of the plastic films can also be processed into film chips that can be used according to the invention.
  • shredded foils which have a very fine and low porosity.
  • the porosity plays a special role in the adhesion of the shredded film to the bitumen.
  • Pre-heated shredded foils are preferably applied to the still hot mastic asphalt surface. Due to capillary action, the film chips suck on the still plastic bitumen surface. In addition to the purely thermal bonding of plastic film and bitumen and any chemical anchoring that may occur, the binding effect of the porosity of the film chips is of particular importance.
  • the method according to the invention can be applied to the most varied types of mastic asphalt, namely those with hard bitumen, medium bitumen and soft bitumen. It is essential to apply the film chips in such a way that they, like the bitumen, are sufficiently soft and plastic.
  • the usual installation temperature of mastic asphalt is approximately 240-250 ° C, depending on the type of bitumen, so that the surface temperature of the surface immediately after its installation is of the same order of magnitude. At this temperature, the bitumen is still sufficiently plastic so that the film chips can adhere to it or be embedded in it.
  • the most favorable temperature of the film chips when they are sprinkled depends primarily on the softening temperature of the plastic film from which the film chips are made.
  • the plastic film should also have a certain plasticity.
  • a preheating temperature can be selected, but at which the plastics should not be overheated until their properties deteriorate. It has proven to be expedient to preheat the film chips 20-70 K above their softening point.
  • the expected surface temperature of the bitumen and the softening point of the film chips provided, as well as the resulting possible preheating temperature, must be taken into account.
  • the bitumen surface is sprinkled with fine minerals or sand - as is generally the case - in order to achieve the required surface roughness and other mechanical properties of the covering.
  • Colored mastic asphalt coverings produced according to the invention are distinguished by excellent load absorption and Abrasion resistance. This is due to the fact that the film chips are slightly sunk in the finished mastic asphalt covering, because bituminous surface that remains free is lifted out of the original surface of the still hot mastic asphalt layer due to the subsequent sanding. Wear begins on the sanded bitumen surface and only when this layer of material projecting slightly beyond the film chips has started to wear does the film chips themselves begin to wear. However, since these are relatively elastic, they can offer additional resistance to an abrasive action.
  • the surface of the mastic asphalt coverings produced according to the invention is rough and does not require any aftertreatment in areas of application where high surface roughness is desirable.
  • the surface of the covering can be provided with a coating in a manner known per se, which is applied either in the form of a polyurethane clear lacquer or a highly viscous wax solution or emulsion. With such a coating, the surface roughness, any voids and cracks can be eliminated.
  • the coverings produced according to the invention have a wide range of applications. They are ideal, for example, for footpaths and cycle paths, in bridge construction, in building construction, e.g. for terraces and balcony coverings, garden paths and flat roofs, to give the latter a green color, for example, and in the manufacture of various sports fields such as tennis courts, but also bowling alleys for which latter application requires the smoothest possible coating.
  • coverings produced according to the invention are also used in a wide variety of industrial applications as floor coverings for machine and workshop halls, warehouses and the like, for marking different areas or routes for forklifts, danger zones or safety distances.
  • the accompanying drawing shows a mastic asphalt covering produced according to the invention in plan view and cross section. The surface area is enlarged disproportionately for clarity.
  • the mastic asphalt base body 1 made of bitumen and minerals is only hinted at.
  • a common mastic asphalt made of medium-hard bitumen with the appropriate grit and grain structure was made and sprinkled with red foil chips, so that 70% of the surface was covered with it.
  • the film chips consisted of a porous plastic film made of polyacrylate. The installation temperature of the mastic asphalt was so high that the surface still had a temperature of 230 ° C when sprinkled with the film chips. The film chips had been preheated to a temperature of 50 K above the softening point.
  • a common mastic asphalt with hard bitumen was used to produce a floor covering for a warehouse.
  • yellow film chips were used to cover approximately 50% of the surface.
  • the film chips consisted of a polyvinyl acetate. In this case two sizes were used, 30% 4-8 mm and 70% 10-12 mm.
  • the mastic asphalt had a surface temperature of 245 ° C. and the film chips had been preheated to a temperature of about 70 K above the softening point of the polyvinyl acetate.
  • a common mastic asphalt with soft bitumen was used to produce a bowling alley. About 30% of the asphalt surface was covered with 6-8 mm film chips. The film chips consisted of polyethylene and were preheated to 30 K above the softening point. During the application, the surface temperature of the mastic asphalt was 220 ° C. After the usual sanding, a coating was applied using a highly viscous synthetic wax. The layer thickness of this coating only needs to be very small, but should compensate for the surface roughness and result in a smooth, almost reflective surface.
  • a common mastic asphalt with soft bitumen was used to produce a sports field, in particular a tennis court.
  • Film chips were applied in an amount of about 85%. They were made of polyacrylate and had a size of 40% 2-4 mm and 60% 8-12 mm. When sprinkling the film chips, the surface temperature of the mastic asphalt was 210 ° C, and the film chips had been preheated to 20 K above the softening point.
