Auger Assembly
Provides mat consistency while minimizing segregation.
The AP-1055D auger drive assembly is
independent of the tractor which allows
the distance between the two feeders to
be significantly reduced. Keeping the
feeders close together allows the flow
from both feeders to blend together
more easily as they discharge into the
auger cavity. The tunnel and auger
designs eliminate voids under the chain
case to minimize segregation.

Gateless Feeders
Variable speed feeders precisely control mix delivery while reducing wear and segregation.
The gateless feeders on the AP-1055D
always run full of mix regardless of the
speed required to fill the auger chamber.
This is typically a slower speed than
would be experienced with a paver
utilizing feeder gates to control mix
delivery rates. By not always having to
run at full speed, feeder component
wear is significantly reduced.
When changes in feeder speed are
required, delivery of mix to the augers is
immediate. This is in contrast to pavers
with gates, where any delivery rate
change is delayed for the length of time
it takes to clear the tunnel of mix from
the previous gate setting.
Running at slower speeds can also help
reduce the opportunity for segregation,
especially when working with larger
stone mixes that have more of a
tendency to segregate.
The auger assembly height can be
hydraulically adjusted 192 mm (7.6").
The ability to raise the auger assembly
simplifies loading and unloading from a
transport vehicle. Also, when working with larger stone mixes, segregation can
often be eliminated or minimized by
raising the augers to allow mix to flow
unrestricted under the auger assembly.
