EPD: Rail expansion joint, 8910 kg/unit, 7850 kg/m3 (voestalpine Turnout Technology Germany)
The products of voestalpine Turnout Technology Germany GmbH are manufactured according to applicable European and international standards, guidelines and specifications. For the use and application of the product, the respective national provisions at the place of use apply, in Germany, for example, the building codes of the federal states and the corresponding national specifications. Rail Expansion Joints (REJ, see EN 13232-8) are used in bridge constructions in order to compensate for the different variations in length between the track system and the bridge, resulting from thermal forces, braking and acceleration forces as well as creeping and shrinkage of concrete. REJ can be supplied for different expansion lengths. The basic geometry of the rail expansion joints is designed for 300 mm, 600 mm and 1200 mm bridge expansion compensation. In special cases, the design and additional components can vary due to customer specifications. REJ can be manufactured and assembled according to the curvature and pre-bent at the factory (if required by design). A possible preassembly takes place in a separate work step within the plants and is not taken into account in this EPD. REJ system are usually installed on concrete sleepers and in special cases on wooden sleepers or directly on special slab track systems. For representation, the data refers to a typical REJ 60-600 of voestalpine Turnout Technology Germany GmbH. The sleepers or a slab track system are excluded from the scope.
