METHOD FOR PRODUCING AND INSTALLING AN ASPHALT BUILDING MATERIAL SUITABLE FOR COLD BUILDING AND CORRESPONDING ASPHALT BUILDING MATERIAL

摘要

The invention relates to a process for the preparation of an asphaltitious asphalt building material for road construction, using a coarse cavity rich cold asphalt mixture comprising a mineral grain and a Bitumenbindemittel for enveloping wetting of the mineral grain in an aqueous emulsion, and a filler for the cavities of a mortar mixture is formed. According to the invention, the solid base materials of the mortar mixture, comprising a mortar binder and fine-grained washed sand, are mixed with the cold asphalt mixture without addition of addition water, wherein the water is removed from the aqueous emulsion of the cold asphalt mixture by the mortar binder. In this way, a cold ausbringbarer and cold installable Asphaltbaustoff is formed, which has a substantially dry and thus free-flowing consistency. The new asphalt building material can be produced directly at the place of application. After cold installation, only a compaction of the Asphaltbaustoffes is necessary, the road surface at the repair site after a short period of time is loadable.
