Triaxial compression tests on granulated scrap tire rubber materials were carried out previously for exploring the possibility of their use as lightweight geomaterials. The results showed in general a low profiled linear load-compression behavior without a peak till up to the high level strain as compared to the early peak and high profiled non-linear load-compression behavior from sand. In the present study, an attempt has been made to improve the load-compression behavior by bonding the scrap tire rubber grains in compressed condition using resin and resin/cement based binding agents. Three types of compressed bonded samples were made from scrap tire rubber grains, and their triaxial tests were carried out using a medium sized triaxial test apparatus under confining pressure of 0.3 MPa. In all the cases, remarkable improvements in the load-compression behavior of scrap tire rubber materials were obtained including a better recovery in unloading the loaded-triaxial sample. The method adopted here is believed to serve as a very useful technique for developing lightweight geomaterials from scrap tire rubber materials.
