Evaluation of Engineering Properties of Sand–Tire Chips Mix
Tóm tắt
Disposal of the scrap tire is of great concern in many countries across the globe. Several studies have been reported in the past for effective reuse of these scrap tires. The use of scrap tire derivatives in civil engineering application is also an emerging field in the recent years. In this study, an experimental testing program was carried out to investigate the behaviour of tire chip, sand and sand–tire chips mix. The study reports the effect of tire chips inclusion on the sand properties. The materials were investigated for different characteristics like specific gravity, void ratio, water absorption, compressibility and shear behaviour. Along with the mixes, behaviour of a single tire chip was also investigated. The tire chips were reported to be highly compressible in nature and possess very low shear strength in comparison to sand. The addition of tire chips to the sand resulted in the decrease in the shear strength and increase in the compressibility of the mix. High plastic strains are also observed for mixes with tire chips content. An optimum sand–tire chips mix is also suggested based on the results of the present study.
