Zusammenfassung:The present disclosure relates to a mother solution free from oil of petroleum origin including at least one oil of vegetable and/or animal origin, from 20% to 50% by mass of polymer, with respect to the mass of the mother solution, with or without at least one cross-linking agent, the oil of vegetable and/or animal origin being acid, with an acid value measured according to the standard NF EN ISO 660 including between 50 and 300 mg KOH/g. This mother solution with a very high concentration of polymer is stable and does not gel and can therefore be diluted and used for preparing cross-linked bitumen/polymer compositions, then bituminous mixes.
