摘　　要：为了研究沥青混合料抗滑级配的评价方法,分析了分形理论在级配评价中的作用和原理;在对常用抗滑级配分形特征参数求取和分析的基础上,探讨了分维数和相关系数在级配评价中的识别作用,在此基础上提出了抗滑级配的双参数定量评价模式。采用此模型估算出的抗滑级配分维数及矿粉质量分数的合理范围分别为2.50-2.60和6%-10%。In order to study the evaluation method of skid resistance gradations of asphalt mixture, the fractal theory was applied to the evaluation, and the principle of evaluation with fractal theory was researched. The fractal characteristic parameters of common skid resistance gradations were presented, the fractal dimensions and relative factors were put forward in the evaluation of skid resistance gradations. The quantitative evaluation model with two parameters of skid resistance gradations was developed. With this model, the variable range of fractal dimension of skid resistance gradations is from 2.50 to 2.60, the variable range of mineral filler mass ratio is from 6% to 10%. 3 tabs, 5 figs, 8 refs.
