WebThe main parameters used in formulating the analysis of the shear strength of soil are the angle of internal friction, the so-called friction angle, and the cohesion. Many researchers have investigated the shear strength of tire waste mixed with natural soil using triaxial tests and/or direct shear tests [30,31]. WebKeywords: Residual soils, direct shear, triaxial, stress path. Introduction The comparison between direct shear box tests and conventional drained triaxial compression tests has been extensively studied for sedimentary soils. For practical purposes both tests give similar values of cohesion and friction angle.
