Abstract
The paper presents the behaviour of sand mixed with tire chips. For this purpose drained triaxial compression tests with strain measurement were conducted on sand mixed with tire chips. The joint effects of chip content (up to 20 %), aspect ratio (up to 2) and con-fining pressure (up to 276 kPa) on the behaviour of sand using multiple regression analysis were investigated. These empirical models may be useful for preliminary esti-mation of energy absorption capacity, deviator stress, initial stiffness and cohesion and friction angle of sand mixed with tire chips.
