Abstract: The invention concerns bituminous compositions comprising:



a bitumen,
a hydroxide XOH, with X═Na, Ca, Mg, Li or K, and
at 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 composition

and the bitumen represents at least 60% by weight of said bituminous composition, their preparation process and their use in road applications.

Abstract: The invention concerns a method for the preparation of a bituminous composition BC comprising the following steps: a) having an intermediary hydrocarbonated composition IC comprising: a hydrocarbonated component selected among bitumen and oils, and a hydroxide XOH with X=Na or K, which represents from 15 to 50% by weight of the total weight of the intermediary hydrocarbonated composition IC, b) introducing the intermediary hydrocarbonated composition IC, into a composition HC of a bitumen, in particular chosen among paving grade bitumen as defined by EN 12591 and polymer modified bitumen as defined by EN 14023. The intermediary hydrocarbonated composition IC as defined in the invention and its uses are other aspects of the invention.
