Abstract: The invention relates to the use, as fluxing agent for bitumen compositions, of at least one compound having the formula (I) R1—C(O)O—R2   (I) where: each of R1 and R2, which may be identical or different, is a linear or branched hydrocarbon chain which does not carry an unsaturated covalent bond, optionally interrupted by one or more oxygen atoms, and optionally carrying one or more hydroxyl functions.

Abstract: 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.

Abstract: The invention relates to the use, as fluxing agent for the production of a hot surface dressing, of an additive for hydrocarbon binder including at least one compound having the formula CH3—X—R—Y—R2 where: R2 is a C1-C11 chain of alkyl type, advantageously methyl; —X— and —Y— are each an ester or amide group with R′═H or C1-C4 alkyl; and —R— is a C1-C10 divalent hydrocarbon chain, optionally interrupted by one or more oxygen atoms; and where the STV pseudo-viscosity measured for said hydrocarbon binder to which has been added 10% by weight of said additive is below 500 seconds.

Abstract: The invention concerns the use as a fluxant agent of at least one compound with the formula (I) R1—X—R—Y—R2  (I) where: R1 and R2, which can be identical or different, are hydrocarbon chains, linear or branched, at C2-C11; each of —X— and —Y—, which can be identical or different, is an —O—(C═O)— group; —(C═O)—O—; —NR′—(C═O)—, where R′ represents a hydrocarbon atom or an alkyl radical at C1-C4, or —(C═O)—NR′—, where R′ represents a hydrocarbon atom or an alkyl radical at C1-C4, the —R— group is a divalent hydrocarbon chain, at C1-C10, linear or branched, and possibly interrupted by one or more oxygen atom(s) in a composition including a hydrocarbon binder for the preparation of the bituminous product based on solid mineral particles in contact with the said hydrocarbon binder, where the said compound of formula (I) is present in the said composition when the said composition is brought into contact with the said solid mineral particles.
