This study investigates the evolving role of GPR in contemporary bridge management by introducing an enhanced methodology based on Multichannel GPR (MCGPR). Through a practical application, this study aims to develop and validate a robust approach that positions MCGPR as a reliable and effective tool for both periodic maintenance and long-term monitoring. The methodology includes conducting repeated MCGPR surveys and analyzing temporal data to identify deterioration trends, verify early signs of structural distress, and guide timely maintenance interventions. By establishing a repeatable process and confirming the consistency of results, the study advances the integration of MCGPR into routine infrastructure assessment programs. Ultimately, this work contributes to more predictive, data-driven asset management strategies that enhance the safety, longevity, and resilience of bridge infrastructure.
