Abstract
1341217 Bituminous compositions SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 16 March 1971 6981/71 Heading C3N [Also in Divisions B1 and C2] A composition comprises a bituminous material and a compound containing a ring system in which there are at least two carbon atoms in the ring and in which there is present the group wherein R 1 and R 2 , which may or may not be the same, represent a hydrogen atom, a hydrocarbon radical or a substituted hydrocarbon radical, in which compound adjacent carbon atoms which are members of said ring and are each linked directly to a nitrogen of said group are not members of a carbocyclic aromatic sixmembered ring. The ring system compound preferably contains an imidazole ring and compounds of this type specified are 4-octyl-2- mercaptoimidazole, 4,5-diheptyl-2-mercaptoimidazole and 4,5-dihydro-2-mercaptoimidazole. The composition preferably contains 0À1-5% by weight of the imidazole compound. The bituminous material may be a distillation bitumen, a semi-blown (pen. 15-300) or blown bitumen (pen. 75-160), a precipitation bitumen such as propane bitumen, and coal-tar oils and residual mineral oil fractions. The bituminous composition may also contain sand, filler, mineral aggregates, pigments, and adhesive agents. In addition the composition may be in the form of cutbacks or aqueous emulsions. In the case of emulsions an organic emulsifier or a clay may also be present.
