Abstract
A placer/spreader for distributing already mixed concrete from an access road to a subgrade path to be paved includes a frame having at least two side bolsters standing parallel to the subgrade path and at least two cross beams spanning the subgrade path for forming a conveyor supporting structure. A roll in/roll out conveyor has a receiving end for receiving already mixed concrete from an access road and a discharge end for discharging already mixed concrete to the subgrade path, this conveyor being hinged to enable conformation to differing access road elevations. One of the two side bolsters defines forward and rear transport attachment points with a spatial interval between the transport attachment points. This spatial interval permits the roll in/roll out conveyor to be supported between forward and rear attachment points.
