Abstract

This paper determined the optimal parameters of the shear emulsion mixer by conducting indoor pretests. The orthogonal experimental method was adopted to analyze the effects of asphalt heating temperature, emulsifier content, and soap pH value on the emulsification effect, with multiple statistical analysis conducted. By employing the range and standardization coefficient as evaluation indicators for the influencing factors, multivariate linear regression was utilized to analyze the experimental data to determine the most sensitive factors affecting the performance of emulsified asphalt in each stage of preparation, and to determine the optimal preparation scheme for emulsified asphalt. The emulsified asphalt performance test was conducted on the asphalt, and the test results show that all indicators meet the specification requirements.
