Based on a self-similar fractal model of JRC profiles, JRC diagram was proposed for a reasonable evaluation of rock joint surface roughness and its size effect. The rock joint surface roughness and its size effect can be evaluated by drawing the fractal model of a rock joint surface profile on the JRC diagram. The fractal model is defined by the steepness and the fractal dimension of the profile. In this paper, variogram method was applied to determine the fractal model and a methodology was proposed to generate the JRC diagram. Moreover, the evaluation method of rock joint surface roughness and its size effect are discussed with considering the interlocking effect of a rock joint.
