The augers distribute asphalt from the hopper in front
of the screed. The screed "floats" on the asphalt as it
passes under the screed plate, leveling the asphalt to
maintain thickness. The end gates contain the asphalt
material at the outer edge of the screed. Use the screed
extensions when paving widths exceeding eight (8) feet.
(Figure 4-46) When adjusted correctly, pressure on
the rear edge of the extended screed is the same as the
rear edge of the main screed, resulting in a smooth mat
the length of the screed.

started, then turn either direction to adjust the angle
of the screed and mat thickness (thicker or thinner)
as needed while paving.
• While paving, check the mat thickness regularly
and make minor screed adjustments using the flight
screw as needed.
