摘要
用红外热成像仪可以直观地检测出沥青路面和桥面铺装层的部分隐性病害,并及早预防.简要介绍了红外热成像技术和红外热像仪的基本工作原理,并对红外热成像技术在检测摊铺温度、脱空病害,以及路面监控等方面的研究现状进行了一些总结;还对红外热成像技术在道路工程应用中的检测结果分析和激励方式等问题进行了展望.
The hidden diseases under the road surface and bridge deck pavement are intuitively detected and early prevented with thermal infrared imager. The basic working principle of infrared thermal imaging technology was briefly introduced in this paper. Besides, the research situation of infrared thermal imaging technology in detecting paving temperature and void disease was summarized. Finally, the results analysis, excitation mode of infrared thermal imaging technology in road engineering were prospected.
