Abstract
Road or pavement surfacing machine which is towed to and from a work site by a truck tractor or the like and is self-propelled by power driven traction wheels on the machine during road or pavement surfacing operation. The traction wheels and the road or pavement surfacing cutter means of the machine are independently vertically adjustable relative to the main load supporting wheels of the machine, and hence relative to one another, by hydraulic actuator means for the cutter means and additional hydraulic actuator means for the traction wheels. These actuator means are independently operable to elevate the traction wheels and surfacing means out of contact with the road during transit of the machine from one location to another, to individually adjust and preset the contact pressure of the traction wheels and surfacing means with the road or pavement being surfaced, and to maintain the preset contact pressures, thereby to maintain the surfacing cutter means in proper cutting contact and the traction wheels in driving contact with the road. The preferred road surfacing machine of the invention has a water tank which contains cooling, flushing and lubricating water for the road surfa…
