Strengthening of railway bridges with UHPFRC overlay
Original language description
In recent years, there has been considerable development of cementitious binder-based materials with exceptional mechanical and durability characteristics – so called Ultra High-Performance Fiber-Reinforced Concretes (UHPFRC). Thanks to their properties, these materials are suitable not only for new structures, details and connections, but also for repairs and strengthening of existing concrete structures. One of convenient methods is strengthening of structures with UHPFRC overlays, i.e. with a thin composite layer of UHPFRC interacting with the existing structure. This method can be used also for railway bridges, at which it is possible by this way to increase their load-bearing capacity in the longitudinal as well as in the transverse direction, strengthen connections of lateral cantilevers (cornices) to the bridge deck and also to increase protection of the deck surface against water etc. For a verfication in a laboratory, a part of a structure at its longitudinal edge with a precast cornice cantilever was chosen. The aim of these experiments is to verify the increase of the resistence of connections of lateral cantilevers to the deck and to verify technology of manufacture. So far, specimens were designed and manufactured and the first experiments has been carried out, verifying resistence of the original connections still without UHPFRC overlay.
