  • Such an adhesive composition film can be produced, for example, in a film factory by at least partial melting of the adhesive composition and subsequent extrusion or calendering. At most, it may also be advantageous if this adhesive composition film contains a fiber fabric or fleece or connected to a fiber fabric or fleece, z. B. an-extruidert, is. After cooling, this film can be easily rolled and thus easily stored or transported. Thus, the adhesive composition is simply on the site and can be unrolled and cut to the required dimensions. This is a very cost and time efficient work step. Basically, the surface of such an adhesive composition film is tack-free.
  • an adhesive composition film has the great advantage that the adhesive composition is distributed over a large area and homogeneously and that the unwanted removal, for example by wind, of the adhesive composition can be largely prevented. It may also be helpful if a pressure sensitive adhesive is applied to one surface of such an adhesive composition film to achieve better fixation of the adhesive composition film to the plastic film during pavement fabrication. In this case, the use of a release paper is particularly recommended to prevent accidental sticking of the individual layers with each other, especially when they are rolled.

This is typically done by melting the adhesive composition in place by means of a warm-up device and, for example, sprayed or whisked in the molten state. Upon cooling, the adhesive composition solidifies into a thin film adhered to the plastic film.

  • the bituminous base layer is heated prior to application to a temperature of typically 140 ° C to 160 ° C and preferably rolled by means of a roll.
  • the application of the bituminous support layer is well known to the person skilled in the art and will therefore not be discussed further here.
  • the base layer can have the other possible components known to those skilled in the art.
  • One skilled in the art will be well aware of the nature and amount of the constituents of bitumen-based compositions used in pavement construction. Of particular importance here is the fact that the support layer usually to a significant extent mineral fillers, especially sand or grit have.
  • the thermoplastic polymer which is solid at room temperature, and any other fusible components of the adhesive composition will melt or melt depending on their melting point. If it melts, they can form a largely homogeneous thermoplastic layer or dissolve in the bitumen near the surface and form a thermoplastic-containing boundary phase layer. Thus, it is well within the spirit of the present invention that the adhesive composition need not necessarily form a discrete and individual layer. If the adhesive composition comprises a chemical or physical blowing agent, upon contacting the molten bitumen with the adhesive composition the propellant is activated and in particular a gas is released. It was found that the adhesion improvement is thereby further improved by observing the proportion of cohesive breakage during testing. The reason for this detention improvement is not yet clear. Gas evolution is believed to modify the bitumen structure at the interface, which in particular achieves better mechanical entanglement of bitumen and adhesive composition.
  • the roadway construction produced in this way has the significant advantage that a long-lasting bond between the individual layers is ensured among each other, that it remains dimensionally stable for a long time even under heavy axle loads.
  • the bond between the plastic film and the bitumen has been greatly improved over the prior art. This results in significantly less fatigue cracks that could affect the Abdichtfunktion the roadway structure.
  • This method presented here thus not only saves time in the manufacture of the roadway structure, but brings further savings in maintenance, since the repair or renewal intervals means can be extended.
  • Another aspect of the present invention relates to the use of the adhesive composition described above in detail for increasing the adhesion of bitumen to plastic.
  • the adhesive layer is in this case based on at least one solid epoxy resin and at least one solid at room temperature thermoplastic polymer.
  • the modified region of the plastic film and / or base layer in the interface region between the plastic film and the base layer is modified here with at least one solid epoxy resin and at least one thermoplastic polymer which is solid at room temperature.
  • either a discrete intermediate layer of the adhesive composition is formed during manufacture and forms the adhesive layer or the plastic film and / or backing layer are modified by the adhesive composition so that the composition of the near-surface region of plastic film and / or backing layer is chemically different from the composition the area remote from the plastic film and / or base layer differs.
  • the thickness of the modified region is highly dependent on the migration ability of the ingredients contained in the adhesive composition and the temperature of the bitumen in the application and its cooling behavior duration. For example, the migration ability is also dependent on the molecular weight and polarity of these constituents. Usually, the boundary of this modified area is not sharp but gradually formed.
