  • Sustainable reuse of Waste Tire Textile Fibers (WTTFs) as reinforcement materials for expansive soils: With a special focus on landfill liners/covers
    Journal of Cleaner Production, 2020
    Co-Authors: S.s. Narani, Mohsen Abbaspour, Elham Aflaki, S. M. Mir Mohammad Hosseini, F. Moghadas Nejad
    Abstract:

    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.

  • reuse of waste tire Textile Fibers as soil reinforcement
    Journal of Cleaner Production, 2019
    Co-Authors: Mohsen Abbaspour, Elham Aflaki, Fereidoon Moghadas Nejad
    Abstract:

    Abstract In recent decades, many geotechnical engineering researchers have used End of Life Tires (ELT) in different shapes for the purpose of soil reinforcement. One of the sub-products that are generated during the treatment of ELT are Waste Tire Textile Fibers (WTTF). These Fibers are classified as special and hazardous wastes. Contrary to international laws, these wastes are burnt or buried, leading to several environmental problems. As an innovative research, reuse of the WTTF to reinforce soils is evaluated through design and performance of a set of laboratory tests. To that end, all mixtures are analyzed under compaction, direct shear, Unconfined Compressive Strength (UCS), California Bearing Ratio (CBR), and Split Tensile Strength (STS) tests after adding 0.5%, 1%, 2%, 3%, and 4% of WTTF on two types of clayey and sandy soils. WTTF are properly capable of improving all strength and ductility parameters of sandy soil. However in clayey soil, in spite of reduction in UCS and CBR, ductility and tensile strength are increased. As a result, instead of burying or burning these wastes, they may be well used for enhancing the mechanical properties of various types of soils. Different behavior of WTTF in clay and sandy soils are investigated by employing fundamental studies performed through optical microscope.
