Use of Waste Tyres in Road Construction

Abstract

The disposal of waste tyres has become a significant environmental challenge due to their non-biodegradable nature and large volumes of accumulation. One innovative and sustainable solution to address this issue is the use of waste tyres in road construction. Incorporating tyre-derived materials, such as crumb rubber and shredded rubber, into asphalt or concrete pavements offers multiple benefits. Rubberized asphalt enhances the durability, flexibility, and skid resistance of roads while reducing the likelihood of cracking and rutting. Additionally, it improves noise reduction and shock absorption, contributing to safer and more comfortable driving conditions. The use of waste tyres in road construction also promotes environmental sustainability by reducing landfill waste and lowering the need for natural aggregates. It can contribute to lower construction costs, as recycled rubber is often more economical than traditional materials. Moreover, rubberized roads have shown improved resistance to temperature fluctuations, making them suitable for regions with varying weather conditions. Despite the numerous benefits, challenges such as initial setup costs, technical expertise, and quality control need to be addressed. Proper design, mixing, and testing processes are essential to ensure the longevity and performance of rubberized roads. Overall, the use of waste tyres in road construction offers an eco-friendly and economically viable solution to the growing tyre disposal problem. It not only enhances road quality and longevity but also supports sustainable waste management practices, making it a promising approach for future infrastructure development.
