Asphalt emulsion-conditioner

摘要: Asphalt emulsion conditioner compositions, derived from spent sulfite liquor lignosulfonates, and asphalt emulsions produced such compositions are provided. The of the slow-setting, anionic type further characterized by their ability to remain stable on storage although with equipment that generates a wide range shearing forces. Such characteristics imparted through use emulsion-conditioner comprising partially desulfonated lignosulfonate, preferably an or nonionic emulsifying agent and, optionally, thickener.
