COMPOSITION OF BITUMEN BASES FOR THE MANUFACTURE OF BITUMEN CONTAINING A SLURRY RESIDUE

摘要

The present invention is directed to a composition formed with a bitumen base comprising at least:A.At least one bitumen base of from 70% to 99% (by weight)^-One Mm and a ductility at 25 and a softening point of not lower than 35 ,B.At least one slurry residue of from 1% to 30% (by weight), resulting from the slurry-phase hydrogenation process,^-One RTI ID = 0.0 25 C /RTI and a softening point of at least RTI ID = 0.0 50 C. /RTI The present invention thus enables upgrading of the final vacuum residue slurry for use in the manufacture of road bitumen.
