Enhancing Concrete Pavement Durability with Recycled Steel Fiber Extracted from Waste Tire
Publication: International Conference on Transportation and Development 2024
ABSTRACT
This study explores the viability of recycled steel fiber-reinforced concrete (RSFRC) as a sustainable alternative to traditional pavement materials. Obtaining recycled steel fibers (RSF) from post-consumer tires and using them in concrete pavement reduces the use of costly asphalt material and the environmental impact of waste tires as well. The research involves experimental and numerical investigations, assessing the mechanical properties of RSFRC through compressive, split tensile, and flexural tests. Results reveal that specimens with 1.5% RSF demonstrate notable improvements, exhibiting a 10.7% increase in compressive strength, 39.3% in split tensile strength, and 10.4% in flexural strength compared to other specimens. Numerical models further highlight the load-carrying capacity advantages of RSFRC pavement sections, presenting a 17% increase over plain cement concrete sections. Additionally, cost and environmental analyses reinforce the economic and ecological benefits of incorporating RSFRC into practical infrastructure, offering valuable insights for sustainable pavement design and construction.
