Compressibility Behavior of Soft–Rigid Granular Mixtures Bound with Polyurethane Binder

Mixtures of recycled tires and granular material have been used for a variety of applications in geotechnical engineering over the years. The characteristics and mechanical properties of sand–rubber mixtures as unbound soft–rigid mixtures have been extensively studied over the years. Research on bound soft–rigid mixtures, however, has been mainly focused on using a brittle binding agent, for example, Portland cement. A very limited number of...
