本文简述了应用超声波无破损检测水泥混凝土路面的内在质量;建立V(L)“声速一距离”曲线及对声速的修正;提出水泥混凝土路面强度和缺陷的超声检测方法和应用实例.
In this paper, the inherent quality of cement concrete pavement with no damage by ultrasonic wave is briefly introduced. The V (L) “sound velocity-distance” curve is established and the sound velocity is corrected. The ultrasonic testing methods and application examples of cement concrete pavement strength and defects are proposed.
