Abstract:

This project had the objectives of developing and characterizing stable modified-sulfur water emulsions using sulfur-extended-asphalt and Sulphlex as base stocks. Anionic and cationic emulsions which had rapid and slow setting characteristics were studied. Standard asphalt emulsion formulations using base stocks containing sulfur produced unstable emulsions which settled excessively. Reaction of a tall oil with sulfur and asphalt separately, and increased emulsifier concentrations resulted in successful emulsions. Settling characteristics were improved by adding a hydroxyethyl cellulose viscosity builder to the continuous phase. Thirteen sulfur-extended-asphalt emulsions arid one Sulphlex emulsion were produced and then characterized using ASTM D244 and several non-standard test procedures. Emulsion properties are compared to· ASTM D977 and D2397 requirements. The study concludes that it is possible to formulate and produce stable modified sulfur-water emulsions using sulfur-extended-asphalt or Sulphlex as base stocks. These emulsions have many characteristics which are comparable to standard asphalt emulsions.
