Abstract
A paternership comprising of the Tecnical University of Graz, The Spittal Technical College, the Dept of Bridge Maintenance of the provincial governmet of Carinthia (Austria) and the company VILLAS Austrial GmbH, are undertaking a project to examine the long term behaviour and performance of bridge deck waterproofing systems. The development of bridge deck waterproofing systems in outlined in relation to the German and, in particular, Austrian market. During rehabilitation of bridge decks, samples of the waterproofing systems were taken and examined for their characteristics. For investigation of waterproofing systems based on polymer bitumen sheets, samples had to be taken from bridge decks being in normal use. No bridge under rehabilitation was available for sampling of those products. Test results demonstrate the improvements in quality of the waterproofinog systems gained by the introduction of polymer bitumen sheets and by the use of epoxy reswin for priming and sealing the concrete substructure. One part of the project deals with the European standardization of waterproofing materials for concrete bridge decks. Waterproofing systems are assessed with appropriately adapated test apparatus in accordance with draft European standards.
