Assessing the performance of geogrids in track overlying soft sub-structures using the rolling load rig facility (RR-TD-9)

Engineering Research & Development (ER&D) was asked to investigate the effectiveness of various measures to improve the durability of track geometry on soft sub-structures. The work was funded by TrainLoad Freight and Network SouthEast under the Cost Effective Sub-Structure Design Project. One part of the project tested the performance of...
