1. Thermoreversibly crosslinked bitumeniferous composition, comprises:

  • -pitch,First additive of-or undersaturated fatty acid ester functional group saturated containing at least one, described fatty acid ester functional group has the hydrocarbon chain of the straight or branched with 4 to 36 carbon atoms optionally replaced by least one hydroxyl,-there is containing at least one the Second addition of the organogel agent of following general formula (I) or (II);



    R 1-CONH-X-NHCO-R 2(I) Wherein, radicals R 1, R 2identical or different and represent the hydrocarbon chain with 4 to 36 carbon atoms independently with X, described hydrocarbon chain is saturated or undersaturated, straight or branched, ring-type or acyclic and be optionally selected from the heteroatoms of O, N and S containing at least one, ■

    R 3-(COOH) z(II) Wherein, R 3for straight or branched, saturated or undersaturatedly contain the hydrocarbon chain of 4 to 68 carbon atoms and z is the integer of 2 to 4.
