Worker Safety, Completed
Remote-Controlled Technology Assessment for Safer Construction
Pavement construction, inspection and maintenance are activities that often require workers near heavy equipment, traffic and dangerous materials. This proximity to potential hazards along with the characteristics of highway and street work zones - transient and restricted areas - increases the possibility of accidents and near-misses. Recent developments in remote-controlled technology can provide workers and inspectors the ability to conduct activities from a safer distance. This project aimed at scanning and evaluating several promising remote-controlled technologies that could be used to improve safety in highway and streets work zones. The technology scanning disclosed over twenty technologies in several levels of development that met this goal. Three technologies were selected for a more detailed review: the Remote-Controlled Ground Penetrating Radar (GPR) for Asphalt Density, the Automated Real-Time Thermal Profiling for Asphalt Paving, and the Autonomous Impact Protection Vehicle. Each technology was evaluated not only based on safety features but also on productivity, data processing, and, especially, requirements for implementation. Workshops with vendors and leading experts were promoted for each technology. Field demonstrations were conducted for the Density Profiling System for determining in-situ asphalt density. Finally, several recommendations for implementation of the selected technologies were provided.
