The present disclosure relates to the use of at least one fatty acid derivative of general formula (1) in a bituminous composition for improving their resistance to aggressive chemical agents, and in particular to hydrocarbons, such as gasolines, gas oils and/or kerosenes, general formula (1) being: with, when n is equal to 0, an X group chosen from the NH2 or NHR3 groups and when n is equal to 1, an X group which represents the -NH-(CH2)m-NH- group, the R1, R2, R3 groups being, independently of each other, saturated or unsaturated, linear or branched hydrocarbon groups with 8 to 24 carbon atoms, m being between 1 and 8.
