4-34 LeeBoy 8515D Conveyor Paver
Operation
815HD (Heavy Duty) Electric
Screed
The optional 815 HD screed is sturdier, heavier and
easier to rebuild. This enhanced screed option can
include power crown, ight screws and electric heating
system (with ve heating elements on the main screed
and one on each hydraulic extension). The sonic auger
mount has adjustable positions. The 815 HD screed
offers two options within this option for even more
robust screed operation: Heated Endgates and Heated
Edge Endgates.
Topcon® sonic grade
control, dual grade
control and slope
options offer paving
professionals screed
control for improving
smoothness along with
assuring accurate slope
and material thickness.
These controllers send
signals to the screed to
precisely maintain mat
thickness and slope as
you pave.
Topcon® Sonic and Dual Grade
Control
Figure 4-65. Sonic Grade
Control
Sonic trackers continuously measure the elevation over
the surface, automatically averaging and adjusting the
tow point cylinder on the paver. The LCD digital display
is easy to see regardless of light conditions.
Choose from one of three options: Sonic Grade Control
(one side); Dual Grade Control or Dual Grade Control
and Slope (both Topcon P-32 systems). The dual
grade controls automatically maintain a set depth on
both ends of the screed. The Dual Grade and Slope
controls maintain a set depth on one end of the screed
and as et slope to the other end.
Most states require this technology for state road paving
jobs to ensure smoothness and continuity on roadways.
Rubber or Steel Track Options
The LeeBoy 8515D paver is equipped with poly-pad
tracks. However, steel or rubber track options are
available in lieu of the poly-pad tracks.
Heated Endgates
The heated endgate
also heats the edge of
the endgate, producing
a smoother joint as you
pave. (Figure 4-66)
(When the heated endgate
is turned on, the leading
heating element turns off
on the side you’re heating.)
With the heated endgate
option(s), additional
switches are added to the
electric heat control box.

Endgate
To operate the heated endgates:
1. Start the paver and idle until the engine reaches
normal operating temperature.
2. Raise the screed plate one or two inches off the
ground.
3. Turn the electric heat control box power ON by
turning the power switch up. (Figure 4-67)
4. Press the Start Heat button. The HEAT ON indicator
light will illuminate and stay on as long as the
element is heating (approximately 20 minutes).
5. Turn the left or right endgate switch up to the ON
position.
6. You can restart the cycle by repeating Step 4 if
needed.
