Self-Healing Roads: A Sustainable Approach to Pavement Longevity

This research examines self-healing roads as a sustainable solution to pavement degradation. Traditional roads deteriorate due to environmental factors and traffic, incurring economic and environmental costs. Self-healing technologies, including capsule-based healing and induction heating, enable automatic pavement repair, extending service life and reducing maintenance. Material analysis shows crack healing rates of up to 80% in optimal conditions. Economic studies indicate 30-45% life-cycle cost reductions despite higher initial costs. Environmental benefits include lower material consumption and carbon emissions. While promising, scalability and performance optimization remain challenges for widespread adoption.
