Slipform Pavers Builds Quality Concrete Roads
Cast in place concrete is
used in very diverse applications for the construction of rigid pavements
because of numerous advantages. Concrete pavements last long and require little
maintenance, if they have been designed properly and executed professionally.
Slip-form paving is most
widely used paving method in modern concrete paving construction. It is very
efficient method and can provide smooth concrete pavement.
Slip-form paving is most
appropriate for larger jobs that require high production rates. It uses
low-slump PCC, provides higher productivity and smooth riding surface.
One of the big advantages
of slip-form paving is economy. The reduction in personnel required and the
speed at which the pavement can be laid often add up to considerable savings.
The name slip-form comes
from operational function of the concrete paver known as Slip-form paver. The
side form of the paver slides across the concrete slab edges to provide smooth
surfaces that consolidate and harden. It does this with the help of an auger
accessory.
The slip-form pavers are
self-propelled equipment and mostly mounted on track. These machines provide a
continuous and seamless concrete pavement surface and by nature give a smooth
surface, without having joints. The main functions of typical track mounted,
self-propelled slip-form paver are screeding, consolidation and initial
finishing but some of the modern slip-form pavers are also designed to accommodate
attachments for performing other slip-form paving operations like concrete
placing, finishing, tinning, curing and texturing thus eliminating the need of
other specialized machines in the paver train.
Slip-form pavers are less
labour intensive as they involve fewer machines and there is no need to provide
for the maintenance, setting and handling of large numbers of side forms.
Slip-form paver with
stringless technology replaces the traditional stringlines with an electronic
tracking process that controls the horizontal and vertical operation of the
slip-form paver. Stringless control systems can accommodate radii or
superelevations automatically according to design data.
Electronic controls and microprocessors have greatly improved the way slip-form pavers operate and perform. Advances in control systems feature self-diagnostics and intelligent electronic-over-hydraulic control.
