Paper Title:
Influence of Mixing Equipment on Asphalt Mixture Segregation
  Abstract

In order to improve mixing quality of asphalt mixture, a method of theoretical analysis and test was used to analyze the effects of negative pressure of drying drum, geometric parameters of mixer and aggregate variation ratio in hot aggregate bins on the segregation of asphalt mixture. Reasonable measures of controlling segregation in the mixing process were given out. Research results indicate that stable negative pressure of drying drum reduce the temperature segregation of asphalt mixture by controlling temperature undulation of hot aggregate and reasonable arrangement of mixing blades cut down material segregation of asphalt mixture with adequate mixing. That isn’t all, delivery proportion of the aggregate in hot aggregate bins and mesh size of vibrating sieve, properly selected according to the gradation of cold aggregate, improve quality and efficiency of asphalt mixture with lower aggregate variation in hot aggregate bins.
