Definitions

  • the invention relates to a bituminous sealing membrane for bridge seals.
  • the mastic asphalt which is hot at 220 to 250 ° C, is usually installed by hand. Because of the high temperatures, the use of conventional, pure or polymer-modified bitumen membranes (FR-A 2 513 282) is not possible.
  • the melting top layer of the sealing membrane mixes with the mastic asphalt (boiling through) and softens it.
  • DD-A 215 559 describes a bitumen mixture which has been modified with radiation-crosslinked polyolefins.
  • the crosslinking is carried out to such an extent that the polymer is still sufficiently soluble in the bitumen.
  • the measure leads to a much greater increase in the pour point than when using non-crosslinked polymers. Due to the increase in viscosity and the associated difficulties in the production of a homogeneous polymer bitumen mixture and the processing of the mass to form sealing membranes, the addition of polymers and the resulting increase in the pour point is limited.
  • a pour point of 140 ° C. is given in example 2.
  • Thermoplastic polymer films e.g. B. based on polyvinyl chloride are not sufficiently thermally stable. Due to the action of heat, elastomer films form wrinkled structures that can be avoided by covering them with paper, but this creates a sliding layer between the concrete slab and the road surface (Bitumen-Teere-Asphalte-Peche, 1972, pp. 170-175).
  • bituminous waterproofing membranes have been proposed for bridge sealing, the upper side of which is laminated with an embossed aluminum foil (DE-OS 2148 448).
  • DE-OS 2148 448 embossed aluminum foil
  • aluminum foils are known to be attacked by de-icing salts.
  • Other metal foils, for example made of stainless steel, are very expensive.
  • the invention has for its object to provide an inexpensive bituminous waterproofing membrane for bridge seals, which ensures a full-surface bond between the bridge construction and asphalt surface, without the risk of softening the asphalt surface.
  • a sealing membrane made of a reinforcement insert (3) which is coated with polymer-modified bitumen materials, at least the upper cover layer (2) consisting of a bitumen modified with radiation-crosslinkable polymers and being spatially cross-linked by electron radiation.
  • bitumen such as, for example, polybutadiene and styrene-butadiene rubber
  • crosslinkable polyolefins such as e.g. B. polyethylene.
  • the ratio of bitumen to crosslinkable polymer is 7/3 to 19/1, preferably 4/1 to 9/1.
  • a rubber content higher than 15% by weight, based on the mixture, leads to a further improvement in the properties, but the sealing membrane can no longer be produced on a conventional roofing membrane system because of the high viscosity of the composition. Then there are more complex manufacturing methods, e.g. B. with the help of calenders, required.
  • the radiation-crosslinked polymer-modified bitumen has a softening point (RuK) of over 180 ° C.
  • RuK softening point
  • the top layer is resistant to de-icing salts.
  • the adhesive connection with mastic asphalt is much stronger than with the MetaiVAsphalt composite. Vapor bubbles from a possibly moist scattering can not arise when applying the mastic asphalt, since only bare or with a thin, easily melting plastic film, eg. B. made of polypropylene, laminated geomembranes are used.
  • the waterproofing membrane can also be welded onto the concrete slab provided with a bituminous primer.
  • a bituminous primer there are two ways to do this. Either the welding layer (4) is applied to the lower cover layer or, as shown in FIG. 2, directly to the underside of the reinforcing insert (3) made of a glass fiber fleece. Since the welding layer (4) retains its adhesive force even after the irradiation, the underside of the web is provided with a release agent.
  • a thin, easily meltable polypropylene film (11) is particularly suitable for this purpose, which mixes with the weld bitumen when it is welded on.
  • the sealing membrane is produced in a conventional manner on a roofing membrane production line in a thickness of 3 to 6 mm. Before being rolled up, the web passes through an electron accelerator. The radiation dose should be at least 5. 10 4 Gy in order to achieve sufficient networking.
  • the weld layer can be applied in particular in the case of thick webs after the irradiation in order to save radiation energy.
  • a polyester fiber fleece (230 g / m 2 ) is impregnated with a mass of 9 parts by weight of distilled bitumen B 200 and 1 part by weight of styrene-butadiene rubber and on both sides with a 2 mm thick layer of 63 parts by weight Bitumen B 200, 7 parts by weight of styrene-butadiene rubber and 30 parts by weight of slate flour with a grain size ⁇ 100 fim.
  • the surfaces are powdered with talc.
  • the web is then placed in an electron accelerator with a radiation dose of 16. 10 4 Gy networked. Before and after the irradiation, web samples are taken to determine the cold stability according to DIN 52123 and the softening point (RuK) according to DIN 52011. The results are compared in the table.
  • a glass fiber fabric (200 g / m 2 ) is impregnated with a mixture of 4 parts by weight of bitumen B 200 and 1 part by weight of polyethylene.
  • the top is 3 mm thick with a mass of 16 parts by weight of bitumen B 200, 4 parts by weight of polyethylene and 5 parts by weight of slate powder, and the bottom is blown with bitumen 100/25 in a thickness of 1 mm coated.
  • the top and bottom are laminated with a thin polypropylene film.
  • the web is exposed to a radiation dose of 6. 104 Gy networked. The test results are compared in the table.
