Definitions

  • the invention relates to a bituminous covering for bridges with superstructures made of concrete, in particular prestressed and reinforced concrete, consisting of the actual surface layer (layer exposed to traffic) made of mastic asphalt or asphalt concrete with a thickness of> __ 35 mm, a protective layer applied under the surface layer Mastic asphalt also> 35 mm thick and a sealing layer of about 4.5 mm thick, the z. B. can consist of a welding track with a carrier insert, the bitumen content in the welding track can be between 60 and 100 wt .-%.
  • the so-called sealing layer is of particular importance for such bridge coverings, because it mediates the transition between the thermally and mechanically flexible top layer and the rigid concrete superstructure of the bridges.
  • the concrete of the bridge superstructure is provided with a seal, which usually has an additional separating layer. This has the task of absorbing or preventing the swelling and bulging when the volume increases, due to moisture evaporating from the concrete, by expanding air and other gases when the temperature rises.
  • a glass fleece which is applied directly to the concrete surface, generally serves as the separating layer. This separation layer is then followed by a layer of asphalt mastic of the thickness mentioned above. For a given bitumen content, additions of fillers are usual, so that sufficient strength against the heat effects of the mastic asphalt as a protective layer and the mastic asphalt or asphalt concrete as a final covering layer is guaranteed.
  • metal corrugated strips for example made of aluminum or copper or stainless steel, in addition to, or instead of, the asphalt mastic.
  • a primer for example on a bituminous basis, is applied to the cleaned and dry concrete surface with about 0.25 to 0.40 kg / m 2 bitumen solution.
  • a separating layer made of perforated glass fleece bitumen membrane, the purpose of which is to relieve the pressure of vapors and gases.
  • the metal corrugated strips are then glued to this, in particular in the pouring and rolling process using an adhesive, for example made of bitumen filled with slate flour or fibrous materials.
  • the subsequent protective layer consists of pure mastic asphalt.
  • bituminous welding sheets are used instead of the casting and rolling process or adhesive process, the surfaces of which are metal and plastic laminated.
  • the perforated glass fleece bitumen sheet is dispensed with and the bitumen welding sheet is flamed on the concrete surface provided with plastic and / or bituminized primer.
  • bituminous covering for bridges with superstructures made of concrete consisting of the actual top layer of poured asphalt exposed to traffic, a bituminous protective layer, predominantly likewise of poured asphalt and one Adjoining sealing layer, which carries a layer made of thermoplastic materials designed as a film, etc.
  • Such a closed covering compound or layers can hardly prevent the occurrence of bloating and thus the formation of overpressure areas due to moisture, air, hydrocarbons, etc. enclosed in the concrete, even with the best possible application of the hot seal consisting of protective layer, sealing layer and thermoplastic layer will.
  • the metal foil itself is not subject to any mechanical stress due to overpressure, so that the aforementioned risk of a reduction in the layer composite, cracks, bubbles, etc. is eliminated.
  • the sealing effect of the sealing and protective layer forming the seal is thus also fully retained.
  • the invention thus relates to a bituminous covering for bridges with superstructures made of concrete, consisting of the actual top layer of poured asphalt or asphalt concrete, a bituminous protective layer, predominantly likewise of poured asphalt, and a subsequent sealing layer forming the transition to the concrete surface, which consists of a bituminous Seal layer is built up.
  • the covering is characterized according to the invention in that the sealing layer is designed as a uniform sheet which has a layer made of metal, in particular aluminum or stainless steel or a polymeric plastic which is stable up to the liquefaction temperature of bitumen, which is perforated or perforated and whose perforations or Perforations are between 1 and 25%, in particular between 5 and 10% of the total surface of the support.
  • the individual holes are mainly statistically distributed. The holes themselves have an average diameter of 0.01 to 1 mm, in particular 0.1 to 0.5 mm.
  • the invention also relates to a method for forming such a bridge covering.
  • support made of metal or metal foil is understood to mean both smooth and structured supports.
  • the term structured encompasses those configurations which have elevations protruding from the plane. Examples of this are corrugations, corrugations, pimples of any geometric habit (squares, rectangles, cones, hemispheres, pyramids, etc.).
  • Aluminum and stainless steel are particularly suitable as the metallic material for the overlay or foil, although copper and similar non-ferrous or light metals are also suitable.
  • polymeric plastics such as hard PVC, post-chlorinated PVC, polyethylene, polyterephthalic acid esters, polyacrylates, etc., as well as corresponding copolymers with two, can also be thermally stable up to the temperature of the hot mastic asphalt (hot for top and protective layer) and more types of monomers are used.
  • the thickness of the support ranges between 0.05 and 1 mm, in particular between 0.10 and 0.30 mm (wall thickness).
  • the size of the free, i.e., made of metal or a polymeric or copolymeric, material after the perforation or perforation in the overlay forming the sealing layer. volatile components of the concrete permeable area is generally about 1 to 25% of the total area of the film, which is opposite to the protective layer. Below approximately 1%, the pressure compensation behavior of the film is considerably restricted and can only be used to a limited extent, while above approximately 25% the mechanical stability of the film is endangered. Especially when using metals such as aluminum or stainless steel, the upper areas of the free area are perfectly acceptable, while the lower limit values are more important for plastics. However, it is generally pointed out that this criterion results from area-wide tests, so that there is no absolute restriction on material and perforation area. In general, open areas between about 5 and 10% of the total surface area of the film are preferred.
  • each hole i.e. whose diameter, ranges between 0.01 and 1 mm and is u. a. also according to the mechanical strength of the film material.
  • the number of perforations per unit area is generally greater than in comparison with perforations of large diameter or opening cross section.
  • the arrangement of the perforation or perforation is in general and preferably statistical, i. H. there is an even distribution over the entire surface facing the protective layer.
  • the geometrical shape of the perforations can be of any type, although a circular habit is preferred for reasons of simple manufacture (drilling or punching). However, other shapes such as cones, squares, rectangles, polygons, slots, etc. are also suitable.
  • the simplest form of the perforated film can occasionally also be formed by a fabric, the mesh size of which determines the free area that allows the passage of volatile components from the concrete.
  • the perforations or perforations in the film have a further, not inconsiderable advantage, which consists in the fact that in the area of the perforations, hot bitumen from the overlying protective layer into the film and / or can penetrate from the welding path into the overlying protective layer and, after cooling, leads to a highly stable anchoring between the protective layer on the one hand and concrete on the other hand, the foil itself in its position tion is consolidated so that there is a continuous stabilization of the entire surface.
  • a further advantage particularly with regard to the stability and the cohesion of the covering, are the fragments remaining when punching out or pressing out the perforations from the film material and still connected to the film surface, the ends of which, like a grater, after application of the mastic asphalt Protective layer protrude into the mastic asphalt (protective layer).
  • Such upward fragments at the edge of the perforations not only lead to a directed passage of the volatile components from the concrete through the perforations, they also form an additional anchoring of the foil, which in this case is made in particular of metal, in the protective layer.
  • the hitherto customary construction of a bituminous covering for superstructures made of concrete initially consists of the top layer (a) made of poured asphalt or asphalt concrete, followed by the protective layer (b), preferably also made of poured asphalt, which can also serve as a seal at the same time, the sealing layer, preferably made of asphalt mastic (c), a separating layer (d) made of raw glass fleece and then the concrete (e) of the bridge board.
  • This version does not use a foil-containing (metal or plastic) sealing layer.
  • the top and protective layers (a, b) correspond to the known structure.
  • a bitumen welding sheet (f) with laminated aluminum foil the welding sheet (f) possibly being glued to the concrete of the bridge board (e) over a full coat.
  • the aluminum foil provides a perfect seal.
  • the aluminum foil is structured, e.g. is designed as a corrugated or knobbed film. A passage of pressure-increasing gases and vapors through the welding path remains blocked.
  • FIG. 2a shows a first embodiment of the covering structure according to the invention.
  • the top and protective layers (a, b) are again largely identical to the corresponding layers according to FIGS. 1a and 1b.
  • the sealing layer or welding track (g) is provided with a film covering which has a statistically distributed perforation (j).
  • this is an unstructured film, plate or tape, e.g. made of aluminum, stainless steel or plastic, the statistical hole distribution of e.g. Embossing, punching or drilling was obtained.
  • the sealing layer or welding track (g) lies on the concrete (e) with the application of a primer (h) made of bituminous adhesive or a plastic adhesive over the entire surface.
  • FIG. 2b shows the structure according to the invention of a covering with structured film (j) and additional separating layer (k) made of raw glass fleece.
  • the film (j) in the special case made of aluminum or stainless steel, is constructed in the manner of a corrugation or knot, in which the perforations are provided exclusively in the elevations or knot surfaces.
  • FIGS. 1 a, 1 b, 2 a and 2 b only show the covering structure schematically, i. That means that both material from the protective layer (b) and from the raw glass fleece (k) intervene in existing empty spaces above or below layers.
  • FIG. 3a The simplest form of the perforated or perforated film is shown in FIG. 3a. This is a flat, non-structured surface (j) with statistically distributed perforations, mainly of the same diameter.
  • the perforation can also have other geometric shapes and e.g. be conical with taper upwards.
  • FIG. 3d A structured, perforated film according to the invention is shown in FIG. 3d.
  • This is a corrugated or dimpled sheet, the uppermost surface areas have the perforation (1) according to the invention.
  • the perforation is not limited to the flat or horizontal areas of the knobs (3), it can also be carried out - alone or in addition - in the inclined surfaces as long as they are in the space above the film (j), i.e. in the direction of the protective layer (b) - see FIG. 2b - opens out.
  • dimpled sheets of this type are not bound to the geometry of FIG. 3d.
  • the upstanding knobs (3) can be larger or smaller than the remaining floor areas. Knobs of different sizes can also alternate with one another distributed over the film surface.
  • the anchoring effect of the perforations is particularly apparent from FIGS. 4 and 5.
  • Liquid bitumen (4) reaches as a welding track (g) with metal foil (j) and raw glass fleece (k) (or another carrier insert, such as glass mesh or polyester fleece), which is connected to the concrete (e) via a primer coat (h). from the protective layer (b) into the perforations (1) of the film (j) and fills the perforations (4 ').
  • the bitumen can also penetrate into the fleece (k) or another suitable carrier insert (4 "), so that a continuous anchoring between the protective layer (b) and concrete (e) after the bitumen (4, 4 ', 4 ") given is. Since the cooling process of the bitumen takes place with a time delay, the evaporating volatile constituents in the concrete are given sufficient opportunity to escape before the bitumen solidifies.
  • This anchoring process is intensified if, as shown schematically in FIG. 5, the fragments discussed above in connection with FIG. 3c are retained at the edge of the perforation.
  • These material fragments (2) form an upward and / or downward exit for the volatile constituents in the concrete and ensure additional, particularly firm anchoring of the film and thus of the entire sealing layer.
  • FIG. 6 shows a particularly advantageous embodiment of the corrugated or nubbed sheets according to the invention as part of the sealing layer, in particular if this is designed as a welding sheet.
  • any geometric shapes can be formed, which are based on parallel to FIG. 6b of parallel corrugations or, according to FIG. 6a, are made up of knobs arranged offset to one another.
  • the perforations (1) are not bound to the uppermost (flat or horizontal) surfaces. They can also be provided in the side surfaces (5, 5a, 5b) and e.g. be designed as slots.
  • the anchoring can also be seen from FIG. 6; process of liquid bitumen penetrating through the perforations (1). This not only fills the gaps (7) - partly as mastic asphalt from the protective layer (b) - it also penetrates into the possibly lower hollow areas (6) of the dimpled sheet (j) and thus conveys the overall effect, such as it was dealt with above with reference to FIGS. 4 and 5. Of course, mutual effects occur in films with bituminous welding sheets.
  • the use of the covering structure according to the invention for concrete (bridges) made of perforated or perforated metal or plastic film in the area of the sealing layer (asphalt mastic plus (if necessary) glass fleece and film) is absolutely reliable over a long period of time and has eliminated all previously known disadvantages of such coverings.
  • the surface is absolutely firm.
