Advanced Highway Maintenance and Construction Technology Applications: The Future Generation of Highway MachineryAuthor/Presenter: West, T.H.; Velinsky, S.A.; Ravani, B.
The Advanced Highway Maintenance and Construction Technology (AHMCT) Center was established in 1989 to investigate the application of advanced automation and robotics to highway maintenance and construction. The Center is jointly managed by the California Department of Transportation (Caltrans) and the University of California, Davis (UCD). Base funding is provided by Caltrans, the Federal Highway Administration, UCD, and other public and private sources. The Center’s research programs use emerging technology, including automation and robotics, to convert many labor-intensive, time-consuming, and tedious operations to safer, faster, and more efficient automated processes. Automation and standardization made possible through technological innovation improve productivity and reliability and reduce transportation system costs. The Center’s five technical areas and sample projects within these areas are described in this article. The five areas are: Roadway Maintenance and Construction Technology (automated crack sealing machine, robotic system for roadway stenciling, laser-guided lane striping system); Roadside Maintenance and Construction Technology (smart herbicide applicator, laser removal of graffiti, teleoperated hazmat system); Structure Maintenance and Construction; Work Zone Safety (teleoperated and automated maintenance equipment robotics, tethered mobile robot); and Construction and Maintenance of Intelligent Transportation Systems.
