Summary: | The invention concerns a fabrication method of a bituminous emulsion, consisting in the use of a primary bitumen emulsion, possibly diluted, characterized by a median diameter of less than 2 μm, as aqueous phase of a secondary bitumen emulsion characterized by a median diameter of more than 2 μm, wherein the final emulsion thus obtained is characterized by a bitumen content of 50% to 95% by weight, a STV viscosity at 40 C through the 4 mm orifice of less than 300 s and a settling tendency of less than 10% as determined by means of assay EN 12847. |
