The objective of the work presented in this paper is to investigate the direct shear strength of a combined sand and rubber tyre mixture for possible use as a lightweight fill material. the paper concentrates on the shear strength of the mixture under relatively high normal stresses in an attem0pt to assess its suitability as a fill material for use in relatively large geotechical engineering projects. The paper presents the results of direct-shear tests on both small particles of 'granular' rubber and small particles of 'shredded' rubber waste, representing the sizes and shapes currently available in the UK. An example slope stability calculation is performed to demonstrate changes in material strength using the widely available computer program SLOPE in the OASYS computer package.
