452.01 Description. This work consists of
constructing a non-reinforced portland
cement concrete pavement on a prepared surface.
452.02 Construction. The requirements of Item 451 apply, except as follows.
Do
not comply with the requirements of 451.08.
Provide
dowels at transverse contraction joints in mainline pavement, ramps,
acceleration/deceleration lanes, or collector/distributor lanes. Dowels
for contraction joints in concrete shoulders on mainline pavement, ramps,
acceleration/deceleration lanes, or collector/distributor lanes are not
required unless the contraction joint is located within 500 feet (150 m) of a
pressure relief joint.
Space
contraction joints according to the standard construction drawings. If
Item 452 pavement is specified for shoulders and is tied
longitudinally to Item 451 or 305 pavement, match the joints
in the shoulder pavement to the spacing and alignment of the adjacent pavement.
Do
not place construction joints within 6 feet (1.8 m) of another parallel joint.
If
making pavement repairs before Department acceptance under 451.17, repair all cracks exclusive of size or
location
452.03 Method of Measurement. The
Department will measure Non-Reinforced Concrete Pavement by the number of
square yards (square meters) completed and accepted in place. The width
equals the pavement width shown on the typical cross-sections of the plans plus
additional widening as the Engineer directs in writing. The Department
will field measure the length along the centerline of each roadway or ramp.
452.04 Basis of Payment. Payment
is full compensation for furnishing and placing all materials, for surface
testing, and for coring the pavement.
For pavement
found deficient in thickness or compressive strength, the Department will pay a
reduced price according to 451.19.
The
Department will not make additional payment over the contract unit price for
any pavement with an average thickness in excess of that shown on the plans.
The
Department will pay for accepted quantities at the contract price as follows:
