Among the construction processes of Portland cement concrete pavement (PCCP), the curing compound spraying process is one of the most important processes. If the curing compound spraying amount does not meet the standard or if the curing compound is not applied evenly, distresses occur at the early age of construction, ultimately causing deterioration in concrete pavement performance. The purpose of this study is to develop a real-time monitoring system for a curing compound spraying process based on the Internet of Things (IoT) and sensing technologies to improve the construction quality of concrete pavement. To achieve the goal of this research, we conducted various laboratory and field experiments. The curing compound spraying amount and sprayed status were measured and analyzed using flowmeters, image acquisition sensors, and an image processing program, and the data were provided to workers in real time and simultaneously transmitted to the IoT cloud to form a database. From this study, it is confirmed that the IoT-technology-based curing compound spraying amount and sprayed status monitoring systems can be successfully established to manage construction quality related to the curing of concrete pavement.
在波特兰水泥混凝土路面（PCCP）的施工过程中，养护剂喷洒工艺是最重要的工艺之一。如果养护剂喷洒量不达标或喷洒不均匀，在施工早期就会出现病害，最终导致混凝土路面性能恶化。本研究的目的是基于物联网（IoT）和传感技术开发一种养护剂喷洒过程实时监测系统，以提高混凝土路面的施工质量。为实现本研究目标，我们进行了各种实验室和现场试验。使用流量计、图像采集传感器和图像处理程序对养护剂喷洒量和喷洒状态进行测量和分析，并将数据实时提供给工人，同时传输到物联网云以形成数据库。通过本研究，证实了基于物联网技术的养护剂喷洒量和喷洒状态监测系统能够成功建立，以管理与混凝土路面养护相关的施工质量。
