ABSTRACT:
A method of producing high quality, homogenous asphalt comprising the steps of mixing and heating a hydrocarbon feedstock not normally suited for asphalt production with elemental sulfur and agitating the resulting mixture. A halide catalyst may be added to the mixture to promote the reaction of the hydrocarbon feedstock with the sulfur. If desired, the agitated mixture may be air blown in any conventional manner to increase its hardness.
