Application of 3D Fractal Dimension in Describing Surface Morphology of Aggregates
The micro-texture of pavement layer aggregate has a direct influence on the skid resistance of pavement. In this paper, the 3D coordinate data of three kinds of aggregates surface is collected based on the surface profiler. Using the box counting method, the MATLAB program is compiled and the 3D fractal dimension of the rock surface is calculated. The results show that the method has good effect on describing the 3D microstructure of the aggregate surface. After that, the difference analysis of fractal dimension of three kinds of different aggregate is carried out. The significant level of microstructure difference between different aggregates is obtained. The results show that there is a significant difference between the surface microstructure of basalt and the other two aggregates. And, there is no significant difference between the surface microstructure of limestone and red sandstone aggregate.
