mat-area-surface deviation which exceeds the tolerance by more than 50
percent shall be corrected to meet the specification requirements.] [The
finished surface will be tested with a straightedge by the Contracting
Officer. Each measurement will be along a line parallel to the centerline.
The smoothness measurements will be at equal distances parallel to the
centerline, not to exceed 8 meters 25 feet. Location and amount of
deviation from straightedge for all measurements will be recorded. When
more than 5 percent of all measurements within a lot exceed the specified
tolerance given in Table V, the computed percent payment for that lot shall
not exceed 95 percent. Any localized areas that exceed the tolerance by
more than 50 percent shall be corrected to meet the specification
requirements.] Corrections required by this paragraph shall consist of
removal and replacement as specified in paragraph CORRECTING DEFICIENT
AREAS.

Thickness Determination
The thickness of the PFC will be determined by the Government on the basis
of measurements made on cores drilled by the Contractor from points where
directed in the pavement selected in a random fashion, with a minimum of
one test per sublot. Cores shall be 100 mm 4 inch in diameter and shall
become the property of the Government. Measurements of individual cores
will be determined in accordance with ASTM C 174/C 174M. The Contractor
shall fill all core holes with hot PFC mixture and compact.
3.10.5
Thickness Deficiency
When the measurement of any core indicates that the pavement is deficient
in thickness by more than 3 mm 1/8 inch, additional cores shall be drilled
parallel to the centerline of the lane at 8 meter 25 foot intervals on each
side of the deficient core until the cores indicate that the deficiency in
thickness is 3 mm 1/8 inch or less. The pavement area determined to be
deficient in thickness shall be removed and replaced in accordance with
paragraph CORRECTING DEFICIENT AREAS. The area of the deficient pavement
shall be considered to be the full paving lane width and midway between
