<p>Bituminous road material obtained by impregnating, coating or contacting an aggregate, a recycling material and a coating aggregate or its mixture with bitumen emulsion (E), comprises bitumen particles of bituminous emulsion comprising a fraction (F) having bitumen particle of 10-40% and average diameter of = 0.6 mu m, preferably 0.1-0.6 mu m, for impregnation, coating or contacting, where the remaining bitumen particle of emulsion has a medium diameter of >= 1 mu m, preferably 1-20 mu m. Independent claims are included for: (1) a road carpet obtained by compacting of the material; and (2) the bitumen emulsion obtained by mixing a bitumen emulsion composed of particles of average diameter of = 0.6 cm (emulsion A) and a bitumen emulsion comprising particles of average diameter of >= 1 mu m (emulsion B), where the bitumen particles have an average diameter of = 0.6 mu m of the emulsions (A) (10-40 wt.%).</p> |
