Stock solutions having high concentrations of polymers comprising oils of plant and/or animal origin for the preparation of bitumen/polymer compositions

The present invention relates to a stock solution containing no oil of petroleum origin, including at least one oil of plant and/or animal origin, 20 to 50 wt % of polymer, relative to the weight of the stock solution, with or without at least one cross-linking agent, said oil of plant and/or animal...

More Information
Summary:The present invention relates to a stock solution containing no oil of petroleum origin, including at least one oil of plant and/or animal origin, 20 to 50 wt % of polymer, relative to the weight of the stock solution, with or without at least one cross-linking agent, said oil of plant and/or animal origin being acid, the acidity index measured according to standard NF EN ISO 660 being 50 to 300 mg KOH/g. Said stock solution having a high concentration of polymer is stable and does not gel and can therefore be diluted and used to prepare cross-linked bitumen/polymer compositions, and then bituminous coated materials.
