Abstract:

Current equipment to measure faulting of jointed concrete pavements at the network level is ineffective and inefficient. One the one hand, joint detection at high speeds is challenging. On the other hand, the actual measurement is not accurate and fails to capture the transverse variability of faulting. In this project, a high- definition, high-speed laser was developed, calibrated and validated in the field. In addition, a methodology for joint detection and a new faulting specification were developed. This research report summarizes the work performed and the main findings of this research project.
