Abstract
Between 40% and 75% by weight of a first bitumen base B1 an asphalt obtained by a solvent deasphalting of a first vacuum residue R1 resulting from the distillation of an effluent hydroconverted by a process for the ebullated bed hydroconversion of a heavy hydrocarbon feedstock, and Between 25% and 60% by weight of a second bitumen base B2 and/or of a flux F, F at least one heavy aromatic cut with a hydrogen content of greater than 8.5% by weight, B2, R1 or a second vacuum residue R2 resulting from a distillation of a crude oil or a mixture of R1 and R2.

Bitumen comprising:
- between 40% and 75% by weight of a first bitumen base B1 consisting of an asphalt obtained by a solvent deasphalting of a first vacuum residue R1 resulting from the distillation of an effluent hydroconverted by a process for the ebullated bed hydroconversion of a heavy hydrocarbon feedstock, B1 having a softening point of between 50° C. and 110° C., and
- between 25% and 60% by weight of a second bitumen base B2 and/or of a flux F, F consisting of at least one heavy aromatic cut having a starting point of greater than 350° C., a 90% distilled point of less than 650° C. according to Standard ASTM D2887 and a hydrogen content of greater than 8.5% by weight, B2 consisting of R1 or a second vacuum residue R2 resulting from a distillation of a crude oil or consisting of a mixture of R1 and of R2,
- it being understood that said bitumen comprises at the most:
- 75% by weight of B1 when said bitumen consists of B1 and F,
- 50% by weight of B1 when said bitumen consists of B1 and B2, and
- 70% by weight of B1 when said bitumen consists of B1 and a mixture of F with B2, and
- the sum of the percentages by weight of B1, B2 and F being equal to 100%.
