| Abstract: | In this paper, ultrasonic cement concrete pavement thickness detector,designation of the wide-band transducer and detecting thickness by ultrasonic echo method are introduced. It is also introduced that tO process the complex echoed signal by separation spectrum can give help to distinguish the location of the echoed signal. The detection error of this instrument used in many projects is about 5%. |
