  • Improving the stiffness of existing railway trackSubscription

    1 October, 2000Updated: 19 February, 2009

    The ISERT (Improving the Stiffness of Existing Railway Track) project aims to devise a method for assessing and improving railway subgrade stiffness without disrupting operational services. The ultimate aim is to achieve a consistent level of subgrade stiffness along a complete route, enabling heavier loads to be carried and reducing maintenance costs. A smooth stiffness transition is required at the approach to underlying, usually much stiffer structures.
