The aim is to generate consistent, repeatable results that enable the transition from sporadic inspections to continuous monitoring. This advancement positions GPR as a viable component of a broader Structural Health Monitoring (SHM) strategy for effective bridge management. Abstract 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 critical insights that support both immediate assessment and have the potential to become a maintenance tool. This paper investigates the practical application of GPR in the context of bridge deck evaluation, tracing its technological evolution, alignment with current industry standards, and performance in real-world field scenarios. A detailed case study is prese nted to illustrate the method’s effectiveness.
