| abstract |
The present invention relates to the use of at least one fatty acid derivative of general formula (1) in a bituminous composition to improve their resistance to aggressive chemical agents, and in particular to hydrocarbons, such as gasolines, gas oils and or the kerosenes, the general formula (1) being: with when n is equal to 0, a group X chosen from the NH or NHR groups and when n is equal to 1, a group X which represents the group -NH- ( CH) -NH-, the groups R, R, R being independently of each other linear or branched hydrocarbon groups, saturated or unsaturated with 8 to 24 carbon atoms, m being between 1 and 8. |
