A process for the transportation and/or storage of road bitumen under cold conditions, including at least one chemical additive chosen from: a general formula compound (I): R 1 —(COOH) z wherein R 1 is a linear or branched, saturated or unsaturated hydrocarbon-based chain including 4 to 68 carbon atoms, and z is an integer ranging from 1 to 4, and a general formula compound (II): R—(NH) n CONH—(X) m —NHCO(NH) n —R′ wherein: R and R′, which are identical or different, contain a saturated or unsaturated, linear or branched, cyclic or acyclic hydrocarbon-based chain having 1 to 22 carbon atoms and optionally including heteroatoms and/or rings having 3 to 12 atoms and/or heterocycles having 3 to 12 atoms; X contains a saturated or unsaturated, linear or branched, cyclic or acyclic hydrocarbon-based chain having 1 to 22 carbon atoms and optionally including one or more heteroatoms and/or rings having 3 to 12 atoms and/or heterocycles having 3 to 12 atoms. |
