Paving Operation
ROLLER ROTATION
• Paving roller rotation can turn either clockwise or
counter clockwise or they can rotate in opposite
directions.
•
Rotate the rollers in the same direction for the first few
passes at the beginning of the pour by using the roller
directional valves, and place the two valve levers in the
same direction .
• Facing the front of the carriage, the rollers will turn
counter clockwise when the carriage travels to the
right and clockwise when the carriage travels to the
left (
SEE BELOW
).
• Have the automatic roller reversing valve in the
“Reversing” position, to allow the roller direction to
change with each pass of the carriage.
• When you have a few passes across the deck, change
the direction of one rollers’ by putting the lever
opposite of the other (
BOTH WERE IN THE SAME
DIRECTION -
SEE ABOVE
)
• Depending on the direction of the carriage travel, for
which lever will be adjusted.
• When putting the automatic roller reversing valve in
the “Non- Reversing” position causes no change to the
roller direction with each pass of the carriage.
• Facing the front of the carriage, the left roller turns
counter clockwise and the right roller turns clockwise.
• The leading roller will consolidate the concrete,
allowing, the trailing roller to pave the surface.
• This roller rotation will allow for the highest production
and sealed surface finish, when pouring a flat bridge
deck or slab.
• Roller rotation direction will depend on which works
better or produces the most satisfactory result due
to varying slumps, mix designs, weather or other
production or delivery variables.
• The carriage automatic pivot will keep the material
to the front of the paving rollers during each carriage
pass, preventing from trailing off to the rear of the
rollers.
• A smooth transition of the pivot device can be achieved
by turning the hex-key set screws clockwise or counter
clockwise to allow greater flow or restrict flow on the
automatic roller reversing valve
