ABSTRACT:
Process for dispersing molten sulphur in a hydrocarbon material, such as asphalt, tar and more particularly bitumen. The dispersion is effected in such a way as to produce an emulsion of sulphur in very fine particles, with dimensions not exceeding 10 microns, in the hydrocarbon material. A turbine with a gap or clearance of about 0.1 to 2.25 mm. is very useful for this purpose. The emulsions obtained are particularly suitable for road surfaces.
