Abstract
The condition assessment of civil engineering concrete-made structures has been a prevalent research area over the last thirty years as a result of concrete deterioration mechanisms that may compromise the integrity and durability of civil infrastructure. Ground Penetrating Radar (GPR) has been extensively used for the inspection and probing of concrete structures. Nevertheless, a comprehensive state-of-the-art review on the developments of condition assessment of concrete-made structures using GPR in a civil engineering perspective is missing in the literature. This paper aims at addressing the abovementioned limitations and contributes to the body of knowledge by leveraging a mixed methodology approach that incorporates the scientometric and systematic analyses on research work related to the condition assessment of civil constructions. Scopus database is used in this study where the state-of-the-art of GPR-based condition assessment models for civil engineering systems is described in conjunction with models' contributions, shortcomings, methodologies, and critiques. These systems include roads, bridges, structures, concrete elements, tunnels, and other civil engineering disciplines such as underground pipes and treatment plants. Finally, future research directions are recommended to guide the civil engineering community in identifying the crucial topics to be explored in the upcoming years.
