| Abstract | Pavement surface properties play critical roles in maintaining proper interaction between tire and pavement, and necessary drainage runoff for both pavement and safety management. Currently, data collection and analysis of pavement surface properties, such as texture and profiling, have primarily relied on single line of measurements using multiple vehicles to obtain a comprehensive evaluation of pavement surface properties. This project serves to demonstrate the use of state-of-the-art 3-D Ultra Laser imaging data collection methodology with integrated data platform, higher data resolution, full-width pavement coverage, less interruption to traffic, and more robust software solutions will result in a more efficient and cost-effective data collection process and may potentially lead to new measurement standards. Specifically, three applications based on 3D Ultra have been investigated in this study for various aspects of pavement surface safety analysis: Effectiveness and performance of High Friction Surface Treatment (HFST) at a national scale, Investigation of geometric texture indicators for pavement safety with 1mm 3D data, Evaluation of pavement surface hydroplaning with 1mm 3D data. |
