Mechanical properties of cemented scrap rubber tyre chips Available to Purchase

Lightly cemented scrap rubber tyre chips have been proposed as a ductile, porous and lightweight geomaterial for various engineering applications. Both drained and undrained triaxial compression tests on the material were conducted. Despite the high flexibility of the rubber chips and hence their higher ductility, the material behaviour was found to be generally similar to that of typical cemented soils. Data points with the same deviatoric strain in p′–q space were linked up to form a series of equi-deviatoric strain lines, and a degradable cohesion intercept is observed in the plot. There was also a tentative critical state line in p′–q–e space (e being the void ratio) that was consistent with the corresponding ‘parent soil' (unbonded, cement-coated chips). In an unloading–reloading stress–strain curve the unloading path was practically identical to the reloading path in a constant-p′ test, but more curved in a consolidated drained test.
