An apparatus for smoothing pavement surfaces comprising:
- a wheeled frame,
- smoothing drum rotatable on a horizontal spinning axis the smoothing drum mounted on the wheeled frame for travel nonparallel to the horizontal spinning axis,
- the smoothing drum having a plurality of spaced cutting teeth, each having a cutting tip of an ultra-hard material,
- the cutting teeth mounted on the smoothing drum such that a multiple of the cutting tips together define a circumferential cutting surface around drum where the tolerance of the radius distance between the horizontal axis and the cutting tips defining the cutting surface is within ⅛ inch,
- the cutting teeth spacing on the smoothing drum such that with regulation of the forward speed of the wheeled frame and the rotational speed of the smoothing drum, overlapping cuts on a pavement surface are formed,
- precision leveling system for mounting the smoothing drum on the wheeled frame, the precision leveler system having profile averaging that is equivalent to or better than profile averaging of a standard smoothing system with an averaging arm of 15 feet or more.
A smoothing drum for smoothing roadway surfaces mounted on a truck or a trailer pulled behind a truck capable of highway speeds, said smoothing drum capable to be positioned up for highway travel or down on hard (non-pneumatic) wheels for smoothing, said truck or trailer also contains structure for cleaning cut material from the roadway in front of rear wheels.
