Abstract: The present invention relates to the field of transport infrastructures and urban planning and development infrastructures, in particular clear or coloured surfacing containing clear binders. More particularly, the present invention relates to a clear binder composition comprising one or more ethylene and alkyl acrylate copolymers having a melt flow rate greater than 2.5 g/10 min and a melting temperature greater than 85° C.

Abstract: The present disclosure relates to the field of so-called “spreading” emulsions of hydrocarbon binder, in particular cationic emulsions of hydrocarbon binders. Such emulsions are useful in the preparation of surface dressings, tack coats, fog seal type surface courses and paver seams. The use of an anionic polymer to improve immediate adhesiveness of a cationic emulsion of hydrocarbon binder to solid particles is particularly described.

Abstract: The present patent application concerns the use of at least one compound of formula (I): R1—O—C(O)—R2??(i) in which: R1 is a linear or branched C1-C6 alkyl group, and R2 is a linear or branched hydrocarbon chain comprising from 2 to 13 carbon atoms and one or more unsaturations, the said unsaturation(s) being one or more carbon-carbon double bonds, as a fluxing agent for hydrocarbon binders.

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.
