COMPOSITION DE BASES BITUME POUR LA FABRICATION DE BITUME COMPRENANT UN RESIDU SLURRY.
The invention relates to a composition formed of bitumen bases which comprises at least from 70% to 99% by weight of at least one bitumen base having a penetrability at 25° C. of less than or equal to 220.10-1 mm and a softening point of greater than or equal to 35° C. and from 1% to 30% by weight of at least one slurry residue resulting from a slurry-phase hydroconversion process. The slurry residue may have a penetrability at 25° C. of less than or equal to 50.10-1 mm and a softening point of greater than or equal to 50° C. Embodiments of the invention make it possible to upgrade a final vacuum residue slurry for use in the manufacture of a road bitumen.
