As infrastructure continues to age worldwide, the demand for effective assessment methods and proactive maintenance strategies becomes increasingly urgent. Ground-Penetrating Radar (GPR) has emerged as a valuable non-destructive testing (NDT) technique for evaluating the condition of bridge decks, offering essential insights that support both immediate assessment and long-term monitoring and maintenance planning.

The paper explores the broader application of GPR in bridge deck evaluation, tracing its technological evolution, examining current industry standards, and showcasing field applications.

This study focuses on the practical application of a Multi-Channel Ground-Penetrating Radar (MCGPR) for the assessment of a reinforced concrete bridge deck. By integrating this advanced technology with an innovative, high-precision scanning methodology, the research demonstrates the potential of MCGPR to serve as a reliable tool for systematic monitoring and ongoing maintenance of bridge infrastructure.
