• Abstract:
  Pavement crack sealing operations remain predominantly manual due to the challenges associated with automation. The research ; performed by the Georgia Tech Research Institute in conjunction with the Georgia Department of Transportation has proved in many ; ways that a commercial-scale automated crack sealing system is viable. Solutions related to the high-speed firing of nozzles, ; automated crack detection, and navigation in a real-time system have been demonstrated on a limited-scale system. ; Additional work remains on the testing of longitudinal crack sealing solutions, and fine tuning of crack detection algorithms. Once ; these issues have been properly addressed, the remaining tasks will primarily be associated with scaling the system from 12" of width ; to a full-lane width. The future of automated crack sealing operations is promising as this research has demonstrated that the technical ; barriers to commercialization have been addressed, thus opening the door for increases in productivity and worker safety.
