3 Selected Technologies The tech scan provided over 23 remote-controlled technologies that showed promising benefits to improve worker safety in highway construction, inspection, and maintenance. It was determined by the project’s Technical Panel that the technologies chosen for the next phase should have a priority to paving work and inspection. Therefore, technologies that were not directly related to pavement work like roadside maintenance, drainage inspection, and land surveying were disregarded from further analysis. The Technical Panel decided to farther investigate two technologies that are of substantial importance for asphalt pavement construction and inspection. The technologies selected focused on the quality control of asphalt paving. The first, Automated Real-Time Thermal Profiling for Asphalt Paving using Infrared Cameras, is able to determine the asphalt mat temperatures continuously during paving. Then, the Remote-Controlled Density Profiling System can provide quick and comprehensive density data for the asphalt layer during and after compaction. The final technology was chosen in leu of the country’s growing interest in connected and automated 24
