Abstract
A method for producing a roadway structure includes: applying pellets of an adhesive composition to a non-tacky surface of a substrate having a support structure, wherein the adhesive composition has at least one solid epoxy resin and at least one thermoplastic polymer that is solid at room temperature; and applying a bitumen-based bearing course. The method permits rapid and efficient production of a roadway structure with good adhesion between the substrate and the asphalt and is suitable in particular for the restoration of asphalt coverings, which must be carried out under time pressure. The application of primer courses is not required.
