401.03.13 Surface Tolerances. The surface will be tested by
the Engineer at selected locations, using an approved 10-foot straightedge
furnished by the Contractor. The variation of the surface from the testing edge
of the straightedge between any two contacts with the surface, shall at no
point exceed 1/4-inch. All humps or depressions exceeding the specified
tolerance shall be corrected by removing defective work and replacing it with
new material as directed.

Final Strike-off, Consolidation and Finishing of Concrete Pavement
f. Straightedge Testing and Surface Correction. After the
floating has been completed and the excess water removed, but while the
concrete is still plastic, the surface of the concrete shall be tested for
trueness with a 10-foot straightedge. For this purpose the Contractor shall
furnish and use an accurate 10-foot straightedge swung from handles 3 feet
longer than one-half the width of the slab. The straightedge shall be held in
contact with the surface in successive positions parallel and perpendicular to
the road centerline and the whole area gone over from one side of the slab to
the other as necessary. Advance along the road shall be in successive stages of
not more than one-half the length of the straightedge. Any depressions found
shall be immediately filled with freshly mixed concrete, struck off, consolidated,
and refinished. High areas shall be cut down and refinished. Special attention
shall be given to assure that the surface across joints meets the requirements
for smoothness. Straightedge testing and surface corrections shall continue
until the entire surface is found to be free from observable departures from
the straightedge and the slab conforms to the required grade and cross section.

Finishing
c. Tolerances. Verification of the
completed surface of the deck, in accordance with the grades and cross slope
specified on the contract drawings, shall be made during placement and again
after the deck has been cured. When the concrete is still plastic, the deck surface
shall be tested with a ten-foot straight-edge and any variance in excess of
1/8-inch in 10-feet shall be corrected immediately. In the event that this
tolerance is not met when tested after the concrete has hardened, variance in
excess of 1/8-inch in 10-feet shall be corrected at the Contractor's expense in
a manner satisfactory to the Engineer.
