摘要
为了分析2D探地雷达在沥青路面病害识别中的适用性,将现场实测的雷达扫描图像与路面显性、隐形病害进行对照评价,结果表明:2D雷达在路面结构内部病害判别上,无法识别毫米级裂缝;2D雷达识别的精度有限,适用于基层内部出现较为严重病害的情况。
In order to analyze the applicability of 2D ground penetrating radar(GPR)in the recognition of asphalt pavement diseases,the field measured radar scanning images were compared with the surface obvious and invisible diseases.The results show that 2D radar cannot recognize the millimeter crack on judging the internal damage of pavement structure.The accuracy of 2D radar recognition is limited,so it is suitable for serious diseases in the base.
