High technology hits the highways

High technology has bypassed real road construction and maintenance until recently. Using emerging technologies such as automation and robotics, researchers at the UC Davis Advanced Highway Maintenance & Construction Technology Center are in various stages of designing and developing nearly one dozen new machines that aim to convert many labor-intensive, time-consuming and tedious operations to automated, safer, faster and more efficient processes. One step away from commercialization, four machines have been tested around California by the state Department of Transportation, a research partner of the UC Davis center. Machines in the field include an automated litter bag and debris-collection machine, a "smart" herbicide applicator, a robotic system for roadway stenciling and an automated crack-sealing machine. Back in the lab, researchers are readying other equipment. An automated machine for safety cone placement and retrieval, a remotely operated front-end loader, a general purpose roadway sign-stenciling machine, and a laser device to remove graffiti from signs and soundwalls are scheduled for Caltrans use in the next two years.
