In this book, the authors present the detailed information on the strength, deformation, and degradation aspects of fresh and recycled ballast under monotonic, cyclic, and impact loading using innovative geotechnical testing devices. A constitutive model for ballast incorporating particle breakage is presented representing a more realistic stressโstrain response. The mathematical formulations and numerical models are validated using controlled experimental simulations and fully instrumented field trials. Revised ballast gradation is described to provide greater track resiliency and extended longevity. The book also provides a detailed description of geosynthetics for substructure improvement considering track deterioration caused by particle degradation, fouling, and impeded drainage. New to this second edition are extensive discussions on subgrade soil stabilisation, causes and mechanisms of soil fluidisation (mud pumping) under cyclic loading, and preventive and remedial measures to alleviate undue instability of ballast tracks.
This book should prove most beneficial for final-year civil engineering students and for postgraduate teaching and learning. It is an ideal supplement for practising railway engineers and researchers engaged in the challenging tasks of future track design for heavier and faster trains.

Dr Wadud Salim is a registered professional engineer in Queensland (Australia) with more than 30 yearsโ experience in the field of geotechnical and civil engineering. He obtained Bachelor of Science in Civil Engineering in 1989, Master of Engineering in 1994, and PhD in 2004. He started his career as a Lecturer in Civil Engineering, then moved to the consulting and construction industry to receive practical experience, returned to research study at the University of Wollongong (Australia) both as a PhD student and as a postdoctoral research fellow, and finally moved to the position of Senior Geotechnical Engineer in the City of Gold Coast, Australia. In his current role, he has carried out geotechnical engineering assessment for thousands of complex development applications and several court cases, which involved very high landslide risk, steep and high cut batters on hill slopes, high retaining walls, soft clay treatments, etc. He published over 20 refereed international conference papers and journal articles. His research interests include rail track geotechnology, slope stability, landslide risk assessment, soft clay stabilisation, and basement excavation stability.
