Shear and compression characteristics of recycled glass-tire mixtures

Abstract

Tire particles in the form of shreds, chips, or crumbs, are normally mixed with sand to make suitable alternative backfill or embankment materials. This mixture of soft (tire) and rigid (sand) particles in their optimum ratio has been shown to provide reasonable engineering performance in terms of strength, permeability, durability, and compressibility. In this study, mixtures of fine recycled glass (FRG) and tire crumbs (TC) were evaluated through isotropic compression tests, as well as consolidated drained triaxial tests under five confinement levels. Four proportions of mixtures with gravimetric TC contents of 10-40% were evaluated in terms of shear and compression response. Results show ..
