Abstract
The present invention relates to bitumen emulsions that can be used in roadmaking applications for the production of cold mixes, emulsion-stabilized gravel and road pavements obtained at ambient temperature, the cohesion of which at young age is substantially improved over the cold mixes, emulsion-stabilized gravel and road pavements of the prior art. These bituminous emulsions are characterized by a median diameter of 0.6 μm or less, and preferably 0.5 μm or less.
