Abstract: The invention consists of a bitumen/resin composite emulsion for a road surface protection layer against the attacks of petroleum derivates, realised by mixing a first emulsion comprising at least one resin with a second emulsion comprising a bituminous binder and a resin crosslinking agent. A pigmentary preparation and/or a load made of a filler or sand or a fine sand or their combinations, can be incorporated to the first emulsion, the second emulsion or into the composite emulsion resulting from the mixture of both emulsions. The loaded composite emulsion enables the realisation of thin film-type surface coatings made of one or several layers.

Abstract: This invention relates to a drying time accelerator for a water-based paint comprising mineral particles, a polymer binder with water-based dispersion and an emulsion polymerization agent, as well as the corresponding paint. The accelerator has a polymeric structure, is water-soluble, comprises cationic charges, and is selected from metallic polychlorides, metallic polyoxychlorides, or synthesis polyacrylamide polymer. The invention also relates to a method for applying a water-based paint according to the invention onto a support, according to which the paint is sprayed onto the support, light-reflecting balls are distributed in the paint, and a drying time accelerator is incorporated into the paint, preferably after distribution of the balls. The application of the invention is to road markings.

Abstract: Bitumen emulsion including bituminous phase having one of pure bitumen, fluxed bitumen, and modified bitumen. The bitumen emulsion also includes an aqueous phase including water and an emulsifying agent. The bitumen emulsion further includes a breaking agent encapsulated in capsules allowing control of breaking of the bitumen emulsion, the control involving rupture of the capsules from a mechanical effect by a mechanical action produced on the bitumen emulsion. Processes of producing a bitumen emulsion. Processes of controlling breaking of a bituminous emulsion.

Abstract: A process and a machine for forming a bonding layer for bonding a bituminous coated material layer on a support. The process includes application of a surface-active agent on the support, application of a bituminous emulsion on the surface-active agent on the support, and application of a breaking agent on the bituminous emulsion to form the bonding layer. A road-type coating made by the process and, therefore, including such a support layer, a bonding layer on the support, and a bituminous coated materials layer on the bonding layer. To perform the process, a machine includes a frame, a displacement mechanism on the frame, a bituminous-emulsion spreader on the frame, a surface-active agent applicator on the frame, and a breaking agent applicator on the frame.
