APPLICATION OF A RANDOM-LAID WEB FOR ROADWAY CONSTRUCTION WITH IMPROVED ADHESION PROPERTIES

摘要

A method for producing a roadway construction, including the steps of applying a random-laid web composed of an adhesive composition which includes at least one solid epoxy resin and at least one thermoplastic polymer solid at room temperature to a substrate including a bearing structure, preferably a concrete structure, and applying a bitumen-based bearing course. The method permits rapid and efficient production of a roadway construction with improved adhesion of asphalt to the substrate. To some extent, primer pretreatment of surfaces is no longer needed.;The present invention relates to a method for producing a roadway construction, comprising the steps of: applying a random-laid web composed of an adhesive composition which comprises at least one solid epoxy resin and at least one thermoplastic polymer solid at room temperature to a substrate comprising a bearing structure, preferably a concrete structure, and applying a bitumen-based bearing course.;The method permits rapid and efficient production of a roadway construction with improved adhesion of asphalt to the substrate.
