On-site inspection of municipal road subgrade and pavement is of great significance for ensuring the quality, safety, and durability of urban road infrastructure. This paper analyzes its key technologies, introduces non-destructive testing methods such as ground-penetrating radar and ultrasonic testing, elaborates on the multifaceted roles of inspection in engineering construction as well as relevant standards, explores site challenges, key technologies, and corresponding measures, and points out future research directions in intelligent sensing and predictive maintenance.
