1. A screed assembly configured to finish a working surface of concrete in a plurality of transverse passes, comprising:
an auger configured for rotation around a first rotational axis, the auger configured to shift an excess portion of the concrete in a paving direction forward of a current transverse pass;
a cylinder configured for rotation around a second rotational axis, the second rotational axis offset from the first rotational axis, the cylinder including a front surface offset behind a front surface of the auger relative to the paving direction, the cylinder configured to compact the working surface; and
a vibratory screed mounted behind the cylinder, the vibratory screed having a rear surface offset behind a rear surface of the cylinder relative to the paving direction, the vibratory screed configured to provide a final finishing of the working surface.
