Abstract (en)

[origin: EP2281948A1] The method involves applying a concrete primer (3) to a concrete support structure (2). A plastic film (4) i.e. polyurethane film, is placed on the primed support structure after priming the concrete support structure. An adhesive composition e.g. chemical blowing agent, containing solid epoxy resin and thermoplastic polymer i.e. ethylene-vinyl acetate copolymer, that is solid at room temperature is applied on the plastic film. A bitumen based carrier layer (8) is formed on the adhesive composition. An independent claim is also included for a roadway structure comprising a support structure.
