Abstract
This study evaluates internally present flaws in RC deck using Ultrasonic Testing. The ultrasonic waves are input from the surface of the asphalt pavement. Wavelet analysis with original mother wavelets CRMW successfully emphasizes the location of the horizontal cracks in the RC deck.
The original wavelets are developed by the reflected waves from the horizontal crack or interfaces that have similar face of the horizontal crack. The wavelet is specialized to detect and extract the horizontal crack. The results show the good agreement with the real location of the horizontal crack.
