Crumb rubber as a sustainable construction material

Abstract

With growing concerns about sustainability and environmental conservation, there has been a significant interest in exploring alternative materials for civil engineering applications. Crumb rubber, derived from recycled tires, has emerged as a promising candidate due to its unique properties and potential to mitigate environmental challenges associated with tire disposal. This paper presents a comprehensive review of the utilization of crumb rubber in various civil engineering applications. In addition to asphalt and concrete, crumb rubber has found applications in various civil engineering products, including sound and vibration-dampening materials, rubberized flooring, green roof systems, and composite building products. These applications leverage the unique properties of crumb rubber, such as elasticity, durability, and thermal stability, to address specific engineering challenges while promoting environmental stewardship. Overall, this review underscores the significant potential of crumb rubber as a versatile and sustainable material for various civil engineering applications. Continued research and innovation in this field are essential to further harnessing the benefits of crumb rubber and advancing the development of environmentally conscious infrastructure solutions.
