Capturing the Moving Deflection Basin Under a Traffic Speed Deflectometer
In recent years, several different high-speed deflection testing devices have become available worldwide. One such device is the Traffic Speed Deflectometer (TSD). ARRB owns and operates two TSDs in Australia and New Zealand and they are also known as iPAVE (intelligent Pavement Assessment Vehicle). This study benchmarks iPAVE results against results obtained with an in-situ array embedded in the pavement at a site established in the state of Queensland, Australia. The embedded array allows for capturing the moving deflection basin under the iPAVe’s wheel(s). The study also focuses on signal processing techniques that can be used to work with geophone data and the integration of pavement velocities to pavement displacements which is the metric commonly used for pavement evaluations.
