Emulsions manufactured with bitumens of different chemical nature have been characterized by two sets of properties: the properties related to the applications (breaking rate, adhesiveness and viscosity); and the electrical interfacial properties measured by electrokinetic potential. From this characterization, the authors have deduced how variations of the surface charge on emulsion droplets determine the breaking rate of the emulsions. In addition, they have found that the chemical nature of the bitumen is a determinant factor for the emulsion properties. The DLVO theory applied to these electrokinetic potential results enables the authors to distinguish each bitumen in a given emulsion formulation by the variations of interaction potentials. An attempt is made to relate these characteristics to the physico-chemical properties of the original bitumen.
