Chemical surface-active agents, which serve as emulsifiers, are classified by the electrochemical charge that is attained when they dissociate in the water solution. In the case of high-float emulsions, the chemical charge is negative. The chemical type and quantity of surface-active agent used in the manufacturing process governs the process in which the resulting asphalt emulsion can be used.
