The 15-year rehabilitation programme of the Department of Transport (DoT) is described, for bringing the UK's stock of trunk road bridges up to current standards, and handling various problems affecting bridges and their components. It is controlled through a comprehensive set of documents, which outline its different technical requirements and organisational procedures. The types of work in the programme are: (1) assessment and strengthening; (2) steady state maintenance; and (3) upgrading. The stages of assessment and strengthening are: (1) older short span bridges; (2) modern short span bridges; and (3) long span bridges. The core of the steady state maintenance work is the continuing repair and replacement of various parts of structures that have deteriorated with time and use. It also includes some preventive maintenance of concrete bridges. The upgrading work is intended to correct deficiencies in certain structures, where current design standards or specifications are not met, mainly those affecting safety and/or durability. The work includes: (1) waterproofing unprotected bridge decks; (2) rehabilitating post-tensioned concrete bridges; (3) strengthening of piers and columns; and (4) health and safety aspects.
