Abstract
Abstract Asphalt emulsifying compositions comprising alkoxylated diquaternary ammonium compounds, the cationic portion of the compound preferably including aliphatic radicals containing from about 12 to about 18 carbon atoms. The compounds may be prepared by treating either a diamine or an alkoxylated diamine with an alkylene oxide in a preferred ratio of 1:8. The emulsion most suitably effected by the present compounds will preferably have a size of less than 10 microns.
