Method for strengthening a road surface, strengthened road surface and an asphalt
concrete therefor |
(57) 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.
