Abstract

Recycling and reuse of waste materials for various civil engineering applications will not only ease problems associated with their disposal but also help preserve dwindling granular materials. In this study, a composite material made up of shredded waste tires and sand is proposed as a fill material in the construction of reinforced retaining walls and reinforced embankments. Accordingly, the pullout resistance of different reinforcements (ribbed metal strip, geogrid, and ladder-type metal) embedded in sand is obtained. In addition, the shear strength characteristics of the mixtures are obtained. Three sizes of tire shreds equal to 9.5 mm in nominal size, and 50–100 mm and 100–200 mm in length are considered. Different mixing ratios of tire shreds in the mixtures are evaluated in the study. For test conditions considered in the study, the pullout resistance factors of metal strips, ladder-type metal, and geogrid reinforcements are proposed. The shear strength of tire shred-sand mixtures in terms of friction angle is found to be in the range 30°–33° in comparison to the end-of-test friction angle for clean Ottawa sand equal to 32°.
