沥青混合料级配分形研究

分形理论作为一种非线性的研究方法,被应用到了许多领域,特别是在材料学方面应用广泛.沥青混合料存在着空隙、集料粒径以及级配等分形,对AC-13、SMA-13、SUPER-13 3种类型沥青混合料的级配分形和分维数范围进行研究.通过研究获得用分维数表征上述3种沥青混合料级配的结果,研究结果表明,分维数和级配的相关性很好,且可以通过维数值反映间断级配或连续级配的特征;可以通过分维数值的大小判定沥青混合料的级配组成,从而对沥青混合料拌合中对配合比控制和检验提供一种新的方法.

Fractal Research on the Graduation of Asphalt Mixture

Fractal theory as a non-line method was applied to many areas; especially in the extensive use of materials sci- ence. There are the fractal gap, the fractal aggregate size and gradation and so on about asphalt mixture. The fractal gradation and fractal dimensions of three asphalt mixture as AC-13, SMA-13, SUPER-13 are studied in the paper. Through research the result that graded characterized of asphalt mixture is shown by the fractal dimension has got. It has shown that fractal dimension is commendably re...
