基于超声多普勒的沥青路面变形研究

Study on Deformation of Asphalt Pavement using Doppler Ultrasonic Technology

在对目前常用的测定沥青路面变形情况方法分析的基础上,提出利用超声多普勒原理对沥青路面变形进行检测。通过对超声多普勒原理、路面变形的分类研究及测试信号谱分析的详细讨论和研究,给出了一种连续、快速检测沥青路面变形情况的方法。

Based on a review of existing approaches, a concept for measuring deformation of asphalt pavement is proposed using Doppler ultrasonic technology in this paper. Following discussions on the principle of Doppler, the classification of the deformation, and analysis of signal spectrum, a continuous and rapid method for the measurement is presented.
