Abstract
A pavement-vehicle convoy for applying a cover layer of a paving material on a traffic area, such as a roadway. The convoy has at least two independently driven units with at least one of the units being a road-surface finisher and each other unit in the convoy being either a finisher or a charger. One of the units is a command unit that has a remote control used to help maintain a predetermined desired longitudinal distance between the convoy units and which can be used to help maintain a predetermined desired lateral distance from a reference line. The remote control includes a speed correcting device that utilizes signals from a distance sensor on at least one of the units that is used to detect changes from the desired distance so that speed correction signals can be generated and provided to an operation control device on at least one of the units. A remote-control link is provided between the operation control device of the command unit and the operation control device of other convoy units so that operation-related signals can be communicated to a master travel controller that controls a travelling mechanism of the command unit and a travelling mechanism of the other convoy units. Control preferably is effected from the driver's cabin of the command unit to the driver's cabin and operation control device of all other convoy units.
