To prepare the cross-linked and/or functionalized Oxidized bitumen 90/10 compositions or the cross-linked and/or functionalized bitumen/polymer concentrates using the mother solution technique, we mix the mother solution that contains the precursor elastomer and, if used, the additional polymers and the cross-linking agent and/or functionalization agent with the bitumen at temperatures ranging between 100° C. and 230° C., more specifically between 130° C. and 200° C. while stirring, this being done, for example, by incorporating the mother solution to the bitumen still being stirred, at temperatures between 100° C. and 230° C. and more specifically between 130° C. and 200° C., then we keep stirring the mixture resulting therefrom and keep it at temperatures ranging between 100° C. and 230° C. and more specifically between 130° C. and 200° C., for example at the temperatures used to make the mixture of the mother solution and the bitumen, for at least 5 minutes, and generally between 10 minutes and 2 hours, to create a product that makes the cross-linked and/or functionalized bitumen https://atdmco.com/penetration/grade-60-70.htmlpolymer composition or the cross-linked and/or functionalized bitumen polymer concentrate.

The quantity of mother solution mixed with the bitumen is chosen to provide the desired quantities, in relation to the bitumen, of precursor elastomer, additional polymer(s) and cross-linking agent and/or functionalization agent, where said quantities fall in the ranges as previously defined.
