Abstract
A sulfur in oil in asphalt blend is disclosed. A polymer-free slurry of solid, elemental, sulfur in liquid oil is used to add sulfur to asphalt. Addition of a slurry of solid sulfur in oil, or oil containing sulfur compounds, permits rapid and effective dispersion of the sulfur component in the asphalt. Uneven mixing, which can occur when sulfur is separately added as a solid, or in molten forms to the asphalt, is avoided. The method is safer because formation of explosive clouds of sulfur dust is avoided.
