FIELD: chemistry.
SUBSTANCE: invention relates to a bituminous composition for use in the field of bitumen, road construction and industry. The bituminous composition comprises a larger portion of at least one bitumen and a smaller portion of at least one chemical additive. The additive is an organogelling agent which creates a network of hydrogen bonds between gelling molecules of the organogel which have molar mass less than or equal to 2000 g·mol-1. Said agent includes at least one hydrogen bond donor group D, at least one hydrogen bond acceptor group A and at least one compatibility enhancing group C which makes the organogelling agent compatible with bitumen chemical compounds. Said agent makes up at least 0.1 wt % of the total weight of bitumen. The invention also relates to a method of producing and using these bituminous compositions in road construction, particularly in producing road binding substances, as well as in industry.
EFFECT: obtaining bitumens which are harder at application temperatures without increasing their viscosity in hot condition.
