Beschreibung
Zusammenfassung:	The invention concerns bituminous compositions comprising:a bitumen,a hydroxide XOH, with X═Na, Ca, Mg, Li or K, andat least one amine additive selected from amines, diamines, polyamines, alkyl amido amines, amidopolyamines and imidazolines, wherein said bituminous composition is substantially free of saponifiable and saponified carboxylic acids, meaning that, if present, the weight of saponifiable and saponified carboxylic acids represents at most 0.01% of the total weight of said bituminous compositionand the bitumen represents at least 60% by weight of said bituminous composition, their preparation process and their use in road applications.
