This paper presents a case study regarding the cooperative use of non-destructive contactless diagnostic investigations as a tool to aid and assist the degradation evaluation of an iconic Roman masonry bridge: Ponte Lucano in Tivoli, Italy. Specifically, unmanned aerial photogrammetric surveys are considered to perform detailed visual inspections and obtain a geometrical 3D model; infrared thermography analyses are carried out to characterize the thermal surface map of the structure detecting anomalies related to material degradation, such as the presence of humidity; ground penetrating radar investigations are performed to improve knowledge of the bridge subsurface structure. The results of the analyses demonstrate that the integration of mentioned diagnostic tools provides information regarding the degradation state of the stones and its causes, as well as regarding the evolution of the structure from its construction up to the present configurations.

本文提供了一个案例研究，该案例研究了无损非接触式诊断研究的合作使用，以辅助和协助评估罗马标志性砖石桥梁的退化评估：意大利蒂沃利的Ponte Lucano。具体来说，可以考虑进行无人航空摄影测量，以进行详细的目视检查并获得几何3D模型；进行红外热成像分析以表征结构的热表面图，从而检测与材料降解有关的异常（例如湿度的存在）；进行了探地雷达的调查，以提高对桥梁地下结构的了解。分析结果表明，所提到的诊断工具的集成提供了有关宝石降解状态及其原因的信息，
