ADDITIFS POUR MATÉRIAU BITUMINEUX COULE A FROID AVEC UN LIANT PARAFFINIQUE A MONTÉE EN COHÉSION RAPIDE
The subject matter of the invention is a cold-poured bituminous material, obtained by mixing a solid fraction, particularly a mineral solid fraction with a cationic bitumen emulsion, the cationic bitumen emulsion comprising an additive, characterized in that the additive is a thermoplastic polymer that is compatible with the bitumen, having at least one carboxylic acid function, the polymer being a polyester, a polyamide, a poly(ester amide), a polyether, a polyacrylate, a polydiene or a copolymer of vinyl and diene monomers. The invention also relates to the use of the bituminous material to make pavement layers, bonding layers or provisional pavement layers and its preparation method; a method for producing a pavement layer or bonding layer comprising the preparation of a cold-poured bituminous layer according to the invention; and the combined use in a cold-poured bituminous material prepared using a non-naphthenic bituminous binder (a) a cationic bitumen emulsion, (b) an additive as defined in the invention, and a mineral additive added to the solid fraction to improve the increased cohesion of the cold-poured bituminous material.
