ABSTRACT:
Automated system for pothole repair including apparatus mounted upon a vehicle for detecting the presence of a pothole and alerting and/or slowing and/or halting the vehicle responsive to such detection. Sensors measure the size of the pothole and/or monitor the filling of the pothole to automatically terminate the filling operation when completed. The sensor outputs are used to determine either level of repair material or volume thereof. The sensors and dispenser (or dispensers) are automatically moved to the desired locations. The filled cavity may be compacted and/or cured. Filler material may be selectively delivered from one or more than one dispensing nozzle.
