Resilient, Sustainable and Smart Ballasted Railway Track explores the optimization of railway ballast tracks to achieve resilience, sustainability, and intelligence in railway infrastructure. It summarizes and examines new technologies and developments that address unresolved rapid defects in track components, such as rail damage, track stability, ballast flight, and ballast fouling. This book discusses the application of innovative materials derived from waste and recycled railway components, including derived aggregates, recycled ballast, Neoballast, and polyurethane (often referred to as ballast glue). This book examines state-of-the-art structural health monitoring techniques, such as smart sleepers, interferometric synthetic aperture radar, ground-penetrating radar, and inspection robots.
