Abstract
An automated pavement repair vehicle includes a vehicle and its various computer-controlled subsystems. The various subsystems, including a vacuum system, heating system and spray patch system, for completing pavement repair, are located on the frame and rear of the truck. A robotic cell at the rear of the truck includes an assembly of retractable doors. The doors are lowered around the pothole to allow control of ambient conditions during the pavement repair procedure.
