Abstract (en)
[origin: EP0863196A1] Process for the preparation of bitumens for road use, characterized in that it comprises the oxidation of a composition consisting of (a) a bituminous component (I) having a content of asphaltenes of between 10 and 50%, a content of aromatics of between 10 and 50% by weight, and a penetration at 25 DEG C of from 1 to 50 dmm, and (b) an aromatic component (II) essentially without asphaltenes and having a content of aromatics of from 80 to 95%, and a viscosity at 60 DEG C of from 100 to 1000 cSt; the weight ratio between the aromatic component (II) and the bituminous component (I) being from 10:90 to 50:50.
