Abstract As a sub-product in the treatment process of End of Life Tires (ELTs), Waste Tire Textile Fibers (WTTFs) are hazardous waste materials that are traditionally buried or burned as opposed to the international laws. Due to the soaring demand for tires and vehicles, disposing of WTTFs imposes a heavy burden on the environment mainly because of two reasons: i) they occupy massive valuable space in landfills, and ii) burning them leads to dangerous gas emission. In this research, the feasibility of reusing WTTFs as reinforcement agents in an expansive soil was investigated through a comprehensive set of laboratory experiments, i.e. standard compaction, Split Tensile Strength (STS), swelling-consolidation, volumetric shrinkage, and desiccation cracking tests. According to the results, WTTFs can enhance all of the investigated geotechnical characteristics of the expansive soil. Moreover, it was proven that WTTF-expansive soil mixtures can be used as a suitable material for impermeable liners and covers in landfills. Therefore, instead of burying or burning them, WTTFs can be competently employed as reinforcement materials in expansive soils.
