Method for strengthening a road surface, strengthened road surface and an asphalt concrete therefor

摘要

The invention relates to a method for strengthening a road surface with an open surface structure, such as very open asphalt concrete (ZOAB), comprising of arranging a layer of asphalt concrete on the road surface, wherein the road surface respectively the asphalt concrete has a grain size distribution around an average such that an open surface structure is formed. The average of the grain size distribution in the road surface is at least substantially a factor of four greater compared to the layer, characterized by applying a layer of asphalt concrete which includes a bituminous emulsion.
