The performance of railway embankment stabilisation measures

Degradation and instability of railway embankments leads to high maintenance requirements and poor ride quality. A range of remedial techniques is available to improve the performance of embankment earth structures. The selection of remedial techniques will inevitably be constrained by available capital budgets and the balance between initial capital outlay and the cost of ongoing maintenance. However, there is little data on the performance improvements achieved by the different remedial techniques. As a result, comparison between schemes on a whole life cost basis is difficult. This paper presents track movement data for a number of embankments where different types of remedial solution have been implemented. A relationship is shown between the stiffness of the remedial scheme, the initial capital cost and the subsequent reduction of differential track movement. This data may help asset managers in client organisations to assess the relative cost effectiveness of different embankment stabilisation solutions. In addition, future research requirements into track performance are highlighted.
