Abstract Used as a modified material，the waste tire granulated rubber was expected to enhance the effectiveness of liner system in landfill and extend the utilization of the waste. The internal strength and interface shear strength tests of waste tire ground rubber and clay mixtures were conducted and the effect of ground rubber on strength properties was studied. The shear strength of the mixtures increases slightly as rubber mixing content increases，and the unconfined compressive strength can meet the requirement in the specification. When the rubber mixing content is 15%，the interface strength of geomembrane/mixtures is higher than that of geomembrane/Kaolin clay. However at the normal stress of 400 kPa，there are stress drop for the interface of geomembrane/mixtures，which results in the lower residual strength. At low normal stresses，the interface strength of GCL/mixtures is slightly lower than that of GCL/Kaolin clay，which is opposite at high normal stresses. The interface strength is lower than the internal strength of the soil. Overall，the effects of the two rubber particle size in this study are not significant，and there are not adverse effects of the waste tire ground rubber on the internal and the interface shear strength.

Key words： soil mechanics waste tire ground rubber clay mixture soil internal strength interface shear strength
