三维雷达在路面基层检测中的应用

The Application of Three-Dimensional Radar in Road Base Detection

无损检测是路面检测发展的趋向,尤其对于半刚性基层路面结构,传统钻芯取样耗费时间长,路面恢复效果不理想,与普通雷达相比较,三维雷达具有检测速度快、精度高、干扰小等优点,在路基病害检测中,具有广泛的应用前景。研究认为,在不影响交通的前提下,选择三维雷达进行路基病害检测具有积极意义。

Nondestructive testing is the trend and direction of the development of pavement testing.Especially for the semi-rigid base pavement structure,the traditional core drilling sampling takes a long time and the pavement restoration effect is not ideal.Compared with the general radar,the three-dimensional radar has the advantages of fast detection speed,high accuracy,small interference,and has a wide application prospect in the detection of subgrade diseases.In recent years,with the increase of highway reconstruction and expansion projects,it is of positive significance to select three-dimensional radar to detect subgrade diseases without affecting traffic.
