FIELD: chemistry.
SUBSTANCE: invention relates to use, in a bitumen composition, of an organic gelling agent derivative, having molar mass of not more than 2000 g/mol and includes at least one hydrogen bond donor D, at least one hydrogen bond acceptor A and at least one compatibiliser C in the bitumen. The compatibiliser C includes a group selected from: at least one straight hydrocarbon chain including at least 4 carbon atoms, at least one aliphatic ring with 3-8 atoms, at least one aromatic ring, at least one aliphatic or partially or entirely aromatic condensed polycyclic system, where each ring includes 5-6 atoms, taken alone or as a mixture, excluding N,N'-ethylene bis(stearamide) and certain aliphatic polyamines.
EFFECT: use of the additive improves resistance of bitumen compositions to petroleum hydrocarbons.
