WebHigh-float (HF) emulsions are dispersions of micron-sized asphalt droplets in water, with a special type of anionic surfactant functioning as a stabilizer. By allowing the water to evaporate from an HF emulsion, what remains is called a HF emulsion residue. WebHigh float asphalt emulsions with high demulsibilities are prepared from asphalts ill-suited for prior art emulsifiers by mixing a combination of fatty acid and the reaction products of fatty acid with acrylic acid, methacrylic acid, fumaric acid, or maleic anhydride in the form of their alkali salts in the soap solution, and adding to the heated …
