ABSTRACT:
Minimum content asphalt-in-water emulsions are prepared employing conductivity measurements. An emulsifying agent e.g., soap and water, a pH adjusting agent e.g., hydrochloric acid, to adjust the pH to be in the approximate range up from about 3 to about 5, and an ionizing salt are brought together and heated to a suitable blending temperature and then blended with asphalt also heated to such a temperature. A method for optimizing conditions to obtain optimum asphalts is set forth.
