It is estimated that about 88% of 104 million scrap tyres generated in Japan in 2006 were either reused or recycled. Because of this, attention has been paid on scrap tyres as new ground material, and recent researches have been moving towards this direction. One method of recycling scrap tyres is by processing them into tyre chips. This paper introduces the results of undrained and drained triaxial compression tests performed to investigate the monotonic shear characteristics of tyre chips-sand mixtures of various combinations. Test results showed that if a small quantity of tyre chips is mixed with sand, the static strength is influenced greatly.
