Quality specification for concrete bridges vulnerable to reinforcement corrosion

Current policies of bridge management system at different road authorities in Croatia are presented in this paper. Although reinforcement corrosion is the major cause of concrete bridge deterioration, quality control plan that would provide efficient and effective bridge management system has not been implemented on satisfactory level to assure pro-active maintenance. Quality control plan for concrete bridges vulnerable to reinforcement corrosion, proposed in this research, includes visual inspection supplemented with the non- destructive testing and structural health monitoring as well as numerical models for service life predictions using recently developed 3D chemo-hygro-thermo mechanical model. The proposed quality control plans will be demonstrated on six concrete bridges of different load-bearing type, age, material and traffic demands exposed to continental and maritime environment.
