Shear waves can be propagated through jointed rocks due to various sources such as earthquakes, mining, and blasting. This research uses the Split Shear Plate (SSP) facility for generating shear waves in rock plates in the laboratory. The SSP apparatus is commonly used for investigating the dynamic properties of materials during wave propagation. The SSP consists of a friction bar, a supporting block, incident and transmitted plates, separated by a joint. Shear wave propagation across jointed rocks with rubber infill materials was studied. Piezoelectric accelerometers were used at different locations within filled rock joints to record the vibrations. Commercially produced synthetic rubber, Styrene Butadiene Rubber (SBR) latex, and naturally abundant available Natural Rubber (NR) latex were chosen as infill materials. Recorded acceleration-time (a–t) histories were used to determine the energy absorption capacity of NR latex and SBR latex across rock joints. SBR latex was found to be more effective in shock absorption than NR latex.
