Oil in water emulsions have outstanding roles in the petroleum industry. Asphalt emulsions vhave unquestionable advantages when compared to asphalt cements, being the main one the considerable lower temperatures of application. Using an anionic-cationic surfactant mixture as emulsifier will have both the advantages of cationic and anionic emulsions. However, cationic-anionic surfactant mixtures have the general tendency to precipitate in some proportions. In a previous work we have studied cationic mixture that does not precipitate in any proportion.
