This study aims to explore and analyze the different influential factors in the process of preparing emulsified bio-asphalt. Colloid Mill was used in this experiment for the process of emulsification with a high speed rotation at 100 ºC. The single factor analysis was adopted in this study to explore the influence of biomass masut and emulsifier on the performance of emulsified bio-asphalt. The experiment set the temperature of 10 ºC, 45~ 50 ºC and 60 ºC , the content of the biomass masut is 10%, 15%, 20%, 25%, 30%, the content of emulsifier is 2.0%, 2.5%, 3.0%, 3.5%, 4.0%, two types of emulsifier named SY-type and MD-type were used in the experiment to compare with the properties of the base asphalt. The remaining amount of evaporation residue of emulsified bio-asphalt on sieve, the penetration, the softening point, the ductility at 10 ºC, the viscosity at 60 ºC, the standard viscosity and the storage stability after 5 days were tested as the indicators to evaluate the performance of the emulsified bio-asphalt. It was found from the experiment that the indicators have a regular curve with the increase of the content of the biomass masut and the emulsifier. The study shows that when the water-oil ratio is 55:45, the content of biomass masut is 15~20%, the content of emulsifier of SY-type is 3.5% and MD-type is 3.0%, the performance of emulsified bio-asphalt plays well, the content is recommended.
