Assessment of UHPFRC based bridge rehabilitation in Slovenia, Two years after application

Within the framework of the EU FP6 Project ARCHES, improved Ultra High Performance Fibre Reinforced Concretes (UHPFRC) based on local components were developed and applied to the rehabilitation of an 36 years old reinforced concrete bridge in Slovenia. Two years after the rehabilitation a thorough visual inspection of the deck and kerbs was performed. During the visual inspection non- destructive and less-destructive on-site tests were performed, such as those to determine the pull-off strength of the UHPFRC layer, as well as its air permeability, the corrosion protection function and the skid resistance were performed. Additionally samples of the UHPFRC were taken for laboratory testing. The paper presents the results of the assessment, including the visual inspection and test results. Based on these, the successfulness of the UHFPRC based rehabilitation is conformed. As a conclusion the benefits and applicability of improved UHPFRC materials are discussed.
