An automated crack sealing system can have substantial economic benefits including reduced labor costs, improved quality, and improved safety. While automating crack sealing is technically challenging for many reasons, technological improvements such as new sensors, microchip computer processors, sensor interpretation algorithms, and manipulator hardware have made automation feasible. In this paper, we consider design issues for automating pavement crack sealing. These considerations have led to the design of a prototype automated pavement crack sealing system which has been implemented in a laboratory setting for concept demonstration and testing. Field tests for the system are ongoing.
