摘要: 根据分形级配理论进行矿料级配设计,把粗级配分形维数Dc、细级配分形维数Df、粗细级配用量比、油石比和压实次数作为沥青混合料空隙率影响因素,采用正交试验分析方法进行试验分析,找出其对沥青混合料空隙的影响程度和变化规律,为优化沥青混合料配合比设计提供依据。

Abstract: Mineral grading design was performed according to the grading fractal theory, in which the coarse grading fractal dimension Dc, fine grading fractal dimension Df and the dosage ratio for coarse and fine grading, asphalt-aggregate ratio and compaction times were taken as factors influencing void ratio of asphalt mixture. Thus the test for analysis was conducted by the orthogonal method to find out their influencing degree on void ratio of asphalt mixture and void change regularity so as to provide basis for optimizing design of mix proportion of asphalt mixture.

Key words: highway engineering, grading fractal theory;mineral aggregate gradation design;the orthogonal experiment;void fraction
