Thermoreversibly Crosslinked Elastic Bituminous Composition

The invention relates to a bituminous composition comprising at least one bitumen and at least one organogelling molecule taken alone or as a mixture, said organogelling molecule being represented by the following general formula (I): where: A represents an acyclic, cyclic or polycyclic, saturated or unsaturated, linear or branched hydrocarbon-based group having 3 to 92 carbon atoms, resulting from the polymerization of the side chains of at least one unsaturated fatty acid, X represents an NH group or an oxygen atom O, R1 represents a group chosen from: a linear or branched hydrocarbon-based group having 2 to 40 carbon atoms, optionally comprising one or more heteroatoms and optionally comprising one or more unsaturations, or a substituted or unsubstituted aromatic group, R2 represents a group chosen from:; a hydrogen atom, a linear or branched hydrocarbon-based group having 1 to 40 carbon atoms, comprising one or more heteroatoms and optionally comprising one or more unsaturations, or a substituted or unsubstituted aromatic group, m and n represent, independently of one another, an integer that varies from 1 to 4, p represents an integer that varies from 0 to 4, q represents an integer that varies from 1 to 4 or a combination of these values, Y represents a group comprising a hydrogen bond donor such as the NH group and a hydrogen bond acceptor such as the C=O group.
