Professor Indraratna is the author of more than 500 publications, including 6 books, about 200 journal papers and 50 invited keynote and plenary lectures. His contributions through research and development towards the understanding of soft soil improvement have been incorporated by numerous organizations into their engineering practices for the design of rail and road embankments.
Dr. Chu is a professor and the holder of James M. Hoover Chair in Geotechnical Engineering at the Iowa State University, USA. Before he joined Iowa State, he was the Director of the Centre for Infrastructure Systems at Nanyang Technological University, Singapore. He has been actively engaged in teaching, research and consulting work in geotechnical engineering in general and soil properties, in-situ and laboratory testing, soil improvement and land reclamation in particular for more than 20 years.
Dr Cholachat Rujikiatkamjorn is an Associate Professor with broad knowledge in soft clay engineering through his work in China, Thailand and Australia. His contributions to the field have also been recognized by several internal UOW, national and international awards, including the 2013 ISSMGE Young Member Award for academic achievements and outstanding contributions to the field of geotechnical engineering. He has published over 120 articles in international journals and conferences.
In Advanced Rail Geotechnology: Ballasted Track, the authors present detailed information on the strength, deformation and degradation, and aspects of fresh and recycled ballast under monotonic, cyclic, and impact loading using innovative geotechnical testing devices. The book presents a new stress-strain constitutive model for ballast incorporating particle breakage and validates mathematical formulations and numerical models using experimental evidence and field trials. The text also elucidates the effectiveness of various commercially available geosynthetics for enhancing track drainage and stability. It presents revised ballast gradations for modern high-speed trains capturing particle breakage and describes the use of geosynthetics in track design. It also provides insight into track design, capturing particle degradation, fouling, and drainage.
This book is ideal for final year civil engineering students and postgraduates and is a solid reference for practicing railway engineers and researchers with the task of modernizing existing track designs for heavier and faster trains.
