BITUMINOUS COMPOSITION WITH THERMOREVERSIBLE PROPERTIES
First Claim
1. A bituminous composition comprising a major proportion of at least one bitumen and a minor proportion of at least one chemical additive, the additive being an organogelator creating a network of hydrogen bonds between organogelling molecules which have a molar mass of less than or equal to 2000 gmol−
- 1, said organogelator comprising at least one hydrogen bond donor D, at least one hydrogen bond acceptor A and at least one compatibilizer C in the bitumen, said compatibilizer C comprising a group chosen from;
at least one linear hydrocarbon chain comprising at least 4 carbon atoms, orat least one aliphatic ring of 3 to 8 atoms, orat least one condensed polycyclic system which is aliphatic, or partly aromatic or also wholly aromatic, each ring comprising 5 or 6 atoms, alone or in a mixture.

Abstract
The invention relates to a bituminous composition that comprises a major portion of at least one bitumen and a minor portion of at least one chemical additive, said additive being an organogelling agent that generates a network of hydrogen bonds between the organogelling molecules constituting the same, and trapping the bitumen phase up to a maximum temperature TR of between 40 and 120° C. The invention also relates to the use of these bitumen compositions in the field of road applications, particularly in the production of road binders, as well as in industrial applications. The invention also relates to a method for preparing these bituminous compositions.
