The Improvement Method of Railway Roadbed

철도노반의 개량방법

A major part of permanent way maintenance effort is justified by inadequacies in the track substructure and in particular in drainage conditions, which need to be put right across the entire network. In most cases nowadays, improvements of the substructure can be carried out on rail to a high standard of quality. However, this entails substantial movements of material for the removal of spoil and provision of new material. In the future, recycling of old material on site, and use of geosynthetics, will be necessary to help considerably reduce this volume.
