Double shear testing was carried out on fully grouted and axially tensioned bolts installed in two different types of three piece concrete blocks. The purpose of the study was to examine the behaviour of reinforced bolts in shear under different axial loading conditions. A total of 22 bolts were tested using three common types of bolts used in Australia. The differentiating factor in bolt selection was the surface profile configuration, and the role of such configuration on the load transfer characteristic of cement/resin and bolt interactions. The influence of different tensional loads on the load transfer characteristics of bolts was also examined. The study showed that the medium strength and the axial tensional load influenced the level of shear load. Higher bolt profile configuration was least affected by the increased axial tensional load changes. There was no clear relationship between the vertical displacement at elastic yield point and each of bolt type, applied axial tensional loads and the medium strength. However, the shear loads were found to increase with increasing tensional loads and that the bolt profile configuration had influenced the shear load.
