Abstract:
1. A method for improving resistance of a bituminous composition to petroleum hydrocarbons, the method comprising adding at least one organogelling molecule into a bituminous composition and contacting the bituminous composition containing the organogelling molecule with petroleum hydrocarbons, the at least one organogelling molecule being represented by general formula (I): where: A represents an acyclic, cyclic or polycyclic, saturated or unsaturated, linear or branched hydrocarbon group, with 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; R R m and n represent independently of each other an integer varying from 1 to 4; p represents an integer varying from 0 to 4; q represents an integer varying from 1 to 4 or a combination of these values; and Y represents a group comprising a hydrogen bond donor and a hydrogen bond acceptor.
