Abstract: In order to verify the effectiveness of multi-scale algorithm on the elastic stiffness parameters of asphalt mixture, this paper analyzes the characteristics of multi-scale algorithm and the fine model of asphalt mixture, and proposes the theoretical method and characterization of multi-scale algo-rithm for random composite materials. The distribution characteristics of fine aggregate of asphalt mixture with different particle sizes are counted, the fine aggregate is randomly generated in the scale area according to the distribution c...
