Zusammenfassung:	The invention relates to a bituminous composition comprising at least one bitumen base, at least one first chemical additive chosen from compounds of general formula Ar1-R1-Ar2 (I), and at least one second chemical additive chosen from a second chemical additive chosen from the reaction products of at least one C3-C12polyol and of at least one C2-C12 aldehyde. The invention also relates to the use of this composition for different industrial applications and as road binder, notably for the preparation of bituminous mixes. L'invention concerne une composition bitumineuse comprenant au moins une base bitume, au moins un premier additif chimique choisi parmi les composés de formule générale Ar1-R1-Ar2 (I), et au moins un second additif chimique choisi parmi un second additif chimique choisi parmi les produits de réaction d'au moins un polyol C3-C12 et d'au moins un aldéhyde C2-C12. L'invention concerne également sur l'utilisation de cette composition pour différentes applications industrielles et comme liant routier, notamment pour la préparation d'enrobés bitumineux.
