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.
