| Abstract: | The five different stone materials were chose to measure their microscopic texture curve with self-developed laser texture meter.By the fractal dimension of the box theory counting method,MATLAB programming was used to calculate different coarse aggregate fractal dimension quickly.The results show that the evaluation method can accurately evaluate the micro-texture of coarse aggregate,and provide more extensive selection of tools and scientific basis for selecting the sliding surface layer. |
| Keywords: | asphalt pavement coarse aggregate micro-texture curve fractal dimension |
