Drawbacks have existed with current pavement crack detection, mapping, and sealing methods which are either solely manual or solely autonomous. A man-machine balance can instead be used, taking advantage of the respective strength of man and machine. This paper describes a man-machine balanced crack sealing process developed for the UT Automated Road maintenance Machine (ARMM). Some of the design issues and tradeoffs involved in balancing human and machine functions for automated pavement crack sealing are discussed when illustrating the ARMM's man-machine balanced control loop. Finally, it is expected that the man-machine control loop devised for the ARMM can also be applied to other infrastructure crack and joint sealing applications, because the specific functions that consist of the man-machine control loop of the ARMM would be commonly required for other sealing operations.
