摘要

Rheological measurement was employed to study the effect of emulsifier content on the properties of asphalt emulsion. Three kinds of emulsifiers are employed, and both temperature and frequency sweep were carried out in this study. Through the analysis of the viscoelastic parameters, the emulsifier content has an obvious influence in the properties of asphalt emulsions. As the content is higher, both the viscosity and modulus increase at a given temperature and/or frequency. The rut factor also increases with the emulsifier content, which indicates an enhanced resistance of emulsified asphalt mixtures to deformation. Rheological results can guide the selection of optimal emulsifier concentration for a given method of preparation. Results of softening point, penetration, ductility and storage stability also show good agreement with the rheological measurements. (C) 2014 Wiley Periodicals, Inc.
