Abstract [en]

Non-Destructive testing (NDT) is an appropriate technique to assess the bridge condition without damaging the bridge. In general, during the measurement procedure, the railway traffic is not interrupted, since the accessibility from one side is sufficient for numerous echo-methods. The NDT-toolbox describes the available NDT-methods and explains application, physical background, limitation, required equipment, time consumption and complexity of the methods on a one-page information. Besides the state of the art, the toolbox informs also, which methods where enhanced and applied within the project Sustainable Bridges (SB 2003-2007).

The NDT-toolbox presents methods for application to bridges made of concrete, steel, including old steel as puddled (wrought) iron or rimmed steel, masonry as well as soil and foundations. For the different materials, the same basic physical principle results in different application with special well-adapted sensor types. The basic physical principle groups of the NDT-methods are:

Visual inspection

Simple inspection

Electromagnetic methods

Acoustic methods

Radiographic methods

Thermal inspection

In tables of the SB-ICA guideline (Helmerich et al. 2007), all NDT-methods (annex 3) are linked to appropriate defect types according to the defect catalogue, attached as annex 2 to this guideline. Vice-versa, the inspector may presume a crack or a hidden defect and via links in tables of the SB-ICA guideline he will find appropriate NDT-methods, useful for further investigation of the defect.
