<p>A small amount of an organosiloxane polymer stabilises an emulsion of sulphur and a bituminous material in which the bituminous material is a continuous phase and the sulphur is a dispersed phase; the stabilized emulsion serves as a binder for mineral aggregates in the manufacture of paving mixtures; the polymer is suitably one having the general formula: where n ranges from 0 to 1000 and R1 and R2 which may be the same or different are selected from the group consisting of alkyl of 1 to 6 carbon atoms, phenyl, phenoxy, benzyl and halo-alkyl of 1 to 6 carbon atoms.</p> |
