BEFORE PAVING SKEWED DECKS
• Before paving skewed decks it is essential that you
determine all of the job specifications and special
details prior to setup of your 6048 Paver . Ask yourself
the following four questions:
1 . What is the skew angle measured perpendicular to
centerline (90 degrees to centerline)
2 . What is the distance between the screed rails,
measured perpendicular to centerline of the deck
3 . Is the deck super elevated
4 . Is the deck crowned
• To determine the length of the machine set at the
required skew angle (A), use the following equation:
(B x L) + C = Total Machine Length,
where,
B = Conversion Factor
L = Rail to Rail Legth, measured perpendicular to the
roadway centerlin (in feet)
C = Extra machine lenght required due to skew
Paving Skewed Decks - Basic Machine
Follow the standard machine setup instructions, initial
roller and drag pan adjustments and roller rotation . Make
sure that the truss and carriage rail have been straightened
per standard machine setup . Mechanically disconnect
the hydraulic skew cylinder and tie it back out of the way .
Manually rotate the lower carriage until the paving rollers
are parallel to the centerline and lock in position using the
skew ring clamps provided with the machine . The drag pan
and burlap/astrograss “H” frames will need to be turned
so that they are parallel to the carriage rail . This allows
the pan and the texturing cloth to follow the skew angle as
the carriage travels across the deck or slab . At this point
the paving rollers need to be stringlined to the carriage rail
so that the rollers are parallel to the carriage rail . Follow
the standard setup instructions for stringlining the paving
rollers . Be sure to run the stringline across the top of the
carriage rail adjacent or parallel to the paving rollers .
Paving Skewed Flat Decks and Super Elevations with
No Crown
Paving skewed flat decks and super elevations do not
require any special equipment. When specifications allow,
the machine can be positioned at an angle approximately
equal to the skew angle . Position the lower carriage so
that the paving rollers are parallel to the centerline of the
deck. The deck should be finished from the leading end of
the machine to the trailing end of the machine . The paving
rollers should be rotating in the same direction and the
automatic roller reversing valve should be set in the “Non-
Reversing” position .
The concrete should be pushed from the low side to the
high side of the elevation and roll over the concrete going
down the super elevation . The machine should pave from
the leading end (must be the low side of the deck) to the
trailing end (must be high side of the deck) .
