Comparison of the Shear Strength Parameters of TDA

ABSTRACT: The increase in the number of discarded tires from vehicles every year is becoming a major issue all over the world. Tires stockpiles and landfills have become a critical issue as it is a rich environment for the breeding of rats and insects, and it is also a real fire hazard that may take up to months to extinguish. One of the safest effective ways of recycling tires is that it gets used as Tire Derived Aggregates (TDA) in the construction industry as lightweight backfilling material and for embankments fills. However, to use any material in the construction industry, several material properties must be evaluated including the shear strength parameters. The main focus of this research is to study the effect of the particle size on the shear strength parameters of TDA using the large-scale direct shear machine. This is a research in progress and more results on other TDA sizes will be provided at the time of the conference.
