A comparative study is conducted to investigate the grouting process in a rock joint. The aim of the present work is to establish a baseline to aid the development of theoretical models that can be applied to design the grouting treatment in a high angle large aperture rock joint. An experimental apparatus, consisting of a joint simulation system, a grouting control system and a data acquisition system, has been constructed with the capability to vary the dip angle and the joint aperture. A transparent viewing window also allows real-time imaging of the grout placement. A series of experiments is performed under pressure control with a dip angle of 0o. Variations of the grout placement radius with time obtained from the experiments are compared with the theoretical predictions based on radial flow of a Bingham fluid in between two parallel plates. The experimental and theoretical results agree in the overall trend. However, the maximum placement radius is overestimated by the theoretical solution. Further development in the theoretical model is needed in order to take into account the complexities such as the interface condition between the grout and the walls and the time-dependent nature in the grout rheology.
