INTERFACE AGENTS FOR THE PREPARATION OF COLD ROAD SURFACINGS

摘要

The invention relates to the manufacture of a bituminous product type mix or surface dressing which includes bringing into contact, at a temperature below 110° C., mineral particles with an emulsion (i) derived from emulsification of a hydrocarbon binder in an aqueous phase at a mixing temperature above the contacting temperature, and (ii) which includes an additive which:forms a homogeneous mixture with the hydrocarbon binder at the mixing temperature;is not compatible with the hydrocarbon binder at the contacting temperature;is used at a content above its solubility in the aqueous medium of the emulsion at the contacting temperature.
