Sažetak
The process of condition assessment of concrete bridges commonly involves a field survey such as visual examination, as well as non-destructive and destructive testing techniques followed by laboratory examination and analytical calculation. Non-destructive test methods are used to determine properties of hardened concrete, properties of steel elements at the time of investigation and to evaluate the condition of concrete in existing structures. They are effective in identifying areas of concrete exhibiting distress and have important role in durability prediction. This paper presents the most suitable non-destructive currently available methods (visual testing, penetrate testing, ultrasonic testing, impact echo, rebar locator, etc.) for evaluating condition state of concrete bridge components such as slabs, girders, piers, column etc. used in Croatia during general inspections. Those methods can be divided in three main groups: methods for concrete evaluation, methods for reinforcement detection and methods for steel evaluation. Paper also shows a description of each method and principle of operation, as well as their application on sixteen concrete bridges in Croatia. Those testing are conducted during regular in-service inspections, condition assessment and determination of remaining service life. Those activities are conducted in Structural division of Civil Engineering Institute of Croatia.
