Influence of Particle Sizes of Asphalt Emulsion on the Properties of Cement and Asphalt Mortar

The influences of particle sizes of asphalt emulsion on the storage stability of emulsion and properties of cement and asphalt mortar were studied. Results indicated that, the storage stability was improved with the decrease of particle size, while the emulsion stability was not improved significantly when the particle size was less than 3μm; the fluidity was improved while the separation rate was increased with the decrease of particle size; the early strength of CA mortar was increased when prepared with the emulsion with larger particle size; while the emulsion with smaller particle size was benefit to the late strength development of CA mortar.
