Advanced rail geotechnology: ballasted track

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. Anew stress-strain constitutive model for ballast incorporating particle breakage is presented. The mathematical formulations and numerical models are validated using experimental evidence and field trials. The effectiveness of various commercially available geosynthetics for enhancing track drainage and stability is elucidated. Revised ballast gradations are presented for modern high speed trains capturing particle breakage. The book also provides extensive description of the use of geosynthetics in track design, and provides an insight totrack design capturing particle degradation, fouling and drainage. This book should prove useful for final year civil engineering students and postgraduates, and for practicing railway engineers with the task of modernizing existing designs for heavier and faster trains.
