Abstract

Certain quality requirements have been set for the waterproofing of bridges. Quality during the construction phase is currently controlled in practice by means of individual adhesive strength tests. Studies performed both in the laboratory and on two test bridges indicate that infrared thermography appears to be applicable for assessing the adhesion of waterproofing sheet membranes on the site of bridge works. The method can be used to localize those areas in which a waterproofing sheet membrane is defectively attached or completely detached from the underlay. The method makes it possible to obtain quickly a mainly general picture of adhesion, so infrared thermography and adhesive strength measurement are methods which complement one another very well. As far as the development of the measuring technique is concerned, the effect of the measuring conditions on the thermographic results should be studied in greater detail and heating methods suitable for field use should be developed.
