Abstract: This paper briefly introduces the application of Ground Penetrating Radar(GPR) in testing the subsurface layers thickness. By testing example, it not only tells us that this method is true in practice, but also gives us a new way in testing subsurface layer thickness

Key words: ground penetrating radar, electromagnetic wave, subsurface layer thickness, testing

摘要： 笔者在文中简要介绍了探地雷达在某公路路面厚度检测中的应用，说叨了用探地雷达方法来检测公路路面 厚度在实际中是切实可行的，为传统的公路路面厚度检测方法又增添了一种新方法。
