Claim 15:
16. A bituminous mix comprising:
(i) a bituminous composition, and
(ii) aggregates, and/or inorganic fillers and/or synthetic fillers, wherein the bituminous composition comprises at least:
a) a bitumen base,
b) a compound of general formula (I):

Ar1-R1—Ar2  (I)

wherein:
Ar1 and Ar2 represent, independently of each other, an aromatic group comprising from 6 to 20 carbon atoms chosen among a benzene nucleus or a system of condensed aromatic nuclei, said aromatic group being substituted by at least one hydroxyl group and optionally by one or more C1-C20 alkyl groups, and
R1 represents an optionally substituted hydrocarbon divalent radical, the main chain of which comprises from 6 to 20 carbon atoms and at least one group chosen from the amide, ester, hydrazide, urea, carbamate and anhydride functional groups,

c) a compound of general formula (II):

R2—(NH)nCONH—X—(NHCO)p(NH)n—R′2  (II)

wherein:
the R2 and R′2 groups, which are identical or different, represent a hydrocarbon chain comprising from 1 to 22 carbon atoms which is optionally substituted and which optionally comprises one or more heteroatoms, and R2 can be H,
the X group represents a hydrocarbon chain comprising from 1 to 22 carbon atoms which is optionally substituted and which optionally comprises one or more heteroatoms, and
n and p are integers having a value of 0 or 1, independently of each other.
