USE OF FATTY ACID DERIVATIVES IN BITUMINOUS COMPOSITIONS TO IMPROVE THEIR RESISTANCE TO CHEMICAL AGRESSIONS AND BITUMINOUS COMPOSITIONS COMPRISING SAID DERIVATIVES

摘要

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)mNH 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.
