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 .
