The use in a bituminous composition of an organogelator molecule of the following general formula (I) is disclosed below: where: A is a hydrocarbon group which can be straight or branched, saturated or unsaturated, acyclic, cyclic or polycyclic, having 3 to 92 carbon atoms, resulting from the polymerization of lateral chains of at least one unsaturated fatty acid, X is an NH group or an oxygen atom O, R1 is a group chosen from: a straight or branched hydrocarbon group with 2 to 40 carbon atoms, optionally including one or more heteroatoms and optionally including one or more unsaturations, or an aromatic group, substituted or otherwise, R2 is a group selected among: a hydrogen atom, a straight or branched hydrocarbon group with 1 to 40 carbon atoms, including one or more heteroatoms and optionally including one or more unsaturations, or an aromatic group, substituted or otherwise; m and n are, separately from one another, an integer ranging from 1 to 4, p is an integer ranging from 0 to 4, q is an integer ranging from 1 to 4 or a combination of the values, Y is a group including a hydrogen bond donor such as the NH grouping and a hydrogen bond acceptor such as the C O grouping, to improve the resistance thereof to aggressive chemical agents, in particular to hydrocarbons such as gasolines, diesels and/or kerosenes.
