Abstract: The texture structure which includes the red and white textures is the most important characteristic of the reticulated red clay. The IPP image processing software is used to study the microstructures of the reticulated red clay in this paper. After the preprocessing which includes the image enhancement, image segmentation and the image binarization, the characteristic parameters that reflecting soil microstructures can be obtained. By studying the fractal dimensions of the reticulated red clay samples, the differences of fractal structure about reticulated red clay in red and white can be differentiated for the engineering applications. The results indicate that the size of the reticulated red clay has the fractal feature and the fractal dimension is between 1.06 and 1.39. The red textured samples have a higher selforganization, gradation and more complex than those of the white textures.
