Road surfacing machine having a front support (e.g. wheels) and a rear support (e.g. a rotatable roller) on which it can move along a road to be surfaced thereby. The body of the machine, which includes a hopper for storing material to be laid and an outlet for discharging it, is supported on the supports. Metering means (e.g. a screed plate) is positioned between the supports and serves to form a layer of selected thickness and shape of the said material on the road base. Bearing means (e.g. horizontal pivots) enable free relative angular movement between the front support on the one side and the metering means and a rear support on the other side about a longitudinal axis and about a transverse axis. Also a road surfacing machine having a front support, a hopper and a screed member, and including profiling means which comprise means for indicating the height and means for indicating the angle of inclination of the screed member.
A road surfacing machine arranged for movement along a road to be surfaced, the machine comprising a body including a hopper for storing material to be laid and outlet means for allowing the discharging of the material from the hopper, a front support and a rear support arranged to support the machine, the front support being situated to travel on the uneven ground to be surfaced, the rear support being situated to travel on the surface laid by the machine, metering means, positioned between the front and rear supports for forming a layer of selected thickness and shape of the material discharged from the outlet means, first bearing means on the front support for free relative angular displacement between the front support and the rest of the machine about a longitudinal axis contained in or parallel to a vertical plane of symmetry of the machine, and second bearing means on the front support for free relative angular displacement between the front support and the rest of the machine about a transverse axis perpendicular to the vertical plane of symmetry of the machine.
