OF WORK.
3.15.9.1
Grade
The final wearing surface of the pavement will be tested for conformance
with specified plan grade requirements, before grout is applied. The grade
will be determined by running lines of levels at intervals of 7.6 m 25 feet,
or less, longitudinally and transversely, to determine the elevation of the
completed pavement surface. Within 5 working days, after the completion of
a particular area, the Contracting Officer will inform the Contractor in
writing, of the results of the grade-conformance tests.
3.15.9.2
Smoothness
All testing shall be performed in the presence of the Contracting Officer.
Detailed notes of the results of the testing shall be kept and a copy
furnished to the Government immediately after each day's testing. Where
drawings show required deviations from a plane surface (crowns, drainage
inlets, etc.), the surface shall be finished to meet the approval of the
Contracting Officer Representative. After the the slurry grout has
sufficiently cured, but not later than 48 hours after placement, the
surface of the pavement shall be tested by the Contractor in such a manner
as to reveal all surface irregularities exceeding the tolerances specified
in table VI. The entire area of the pavement shall be tested in both a
longitudinal and a transverse direction on parallel lines. The transverse
lines shall be 8 m 25 feet or less apart, as directed. The longitudinal
lines shall be at the centerline of each paving lane for lines less than
6.1 m 20 feet and at the third points for lanes 6.1 m 20 feet or greater.
Other areas having obvious deviations shall also be tested. Longitudinal
testing lines shall be continuous across all joints. The straightedge
shall be held in contact with the surface and moved ahead one-half the
length of the straightedge for each successive measurement. The amount of
surface irregularity shall be determined by placing the freestanding
(unleveled) straightedge on the pavement surface and allowing it to rest
upon the two highest spots covered by its length, and measuring the maximum
gap between the straightedge and the pavement surface in the area between
these two high points.
3.15.10
Job-Mix-Formula
Routine testing for acceptability of work shall be performed by a Corps of
Engineers certified commercial laboratory hired by the contractor and
approved by the Contracting Officer. Additional tests required to
determine acceptability of non-conforming material shall be performed by
the Contractor at its own expense. The contractor shall use a Marsh Flow
Cone for testing the viscosity of grout.

ACCEPTABILITY OF WORK
3.16.1
General
When a section of pavement fails to meet the specification requirements,
that section shall be totally removed and replaced at the Contractor's
expense. The Contracting Officer reserves the right to sample and test any
area which appears to deviate from the specification requirements.
