Paving Operation
PAVING CURVES
• Mark an equal number of spaces on the inner curve (1
to 2 feet spacing), know the length or distance of the
inside.
• Count the number of spaces on the inner curve and
mark the same number of spaces on the outer curve.
The length of these spaces will vary with the length of
the outer curve section (SEE PICTURE).
• To keep the machine square throughout the pour, the
operator will at times place the machine direction
control lever in the neutral position allowing a longer
amount of travel for the outer curve end of the machine
• The front edge of the machine wheels of both the inner
and outer ends needs to stay aligned with the marks
spaced on the inner & outer rail.
MACHINE ADVANCEMENT
• The operator will pace the machine travel
advancement to coincide with the placement of the
concrete,
• Place concrete no more than 5 to 8 feet in front of the
machine.
• Average advancement of the machine can vary from 3
to 8 inches for each carriage pass.
• In hot, windy weather, this will insure fresh concrete
will move into the paving rollers before any drying
occurs.
• Always keep the deck wet.
CARRIAGE TRAVEL SPEED
• Slower carriage travel will allow the paving rollers to
have longer contact with the surface thus allowing the
concrete to seal better and provide a more uniform
surface finish result.
• When paving with high slumps or mix designs with
super plasticizer, slowing the carriage travel speed will
be beneficial.
• To slow the carriage travel, use the carriage speed
control valve located on the operator’s console.
• The engine should be running at full throttle for full
RPM’s. (2900 to 3300).
• This rate will allow the carriage to travel on average,
approximately 80 to 90 feet per minute transversely
across the machine.
