Abstract
This review covers assessment, stability management and structural evaluation of strengthened concrete bridge structures, with a focal point on both contemporary practice and future instructions within the discipline. It starts with an overview of purposeful, cloth and structural classes used to contextualize overall performance requirements for highways, railways, pedestrian and utility bridges. The evaluation highlights the use of visual inspection blended with focused non-unfavorable testing methods, such as infrared thermography, ground-penetrating radar, shock echo and ultrasonic pulse pace. It also discusses electrochemical techniques for assessing reinforcement corrosion, such as half-cell potential, electrical resistivity, linear polarization resistance, and electrochemical impedance spectroscopy. Emphasis is placed on how transport-related indicators – such as absorption, voids, resistivity and chloride migration – relate to corrosion risk. In addition, the review provides a summary of current applications of computer vision analytics and UAV (unmanned aerial vehicle) or close-range photogrammetry pipelines. The aim is to extend coverage, increase safety and enable quantitative fault mapping. However, practical limitations such as navigational challenges, light and wind conditions and uniformity in data collection are also taken into account. To reconcile observed responses with analytical assumptions, static and dynamic load testing has been integrated with calibrated finite-element modeling (eg CSIBridge). This approach supports usability verification and boundary condition updating. Finally, a life-cycle framework is proposed to integrate various maintenance, repair and strengthening options – for example, ultra-high performance concrete (UHPC).
