Rapid Detection of Concrete Joint Activation Using Normalized Shear Wave Transmission Energy
The Illinois Center for Transportation at the University of Illinois at Urbana-Champaign has released a report that tests a one-sided non-destructive ultrasonic measurement technique used to detect the existence of a contraction joint crack. A rapid and reliable method to detect the activation of contraction joint cracks is needed in order to assess the effectiveness of sawcut depth and timing on new concrete pavements and for forensic investigation when premature slab cracking occurs.
