PART 3 - EXECUTION
3.1 GENERAL
A. Equipment: All equipment necessary for the proper construction of the
work shall be on the project, and in first-class working condition.
I--
B. Limits of Construction: The Contractor shall construct the base to the full
width shown on the Drawings.
3.2 PERFORMANCE
A. Excavation: The area in which the widening is to take place and the
limerock base is to be placed shall be excavated to the depth and
dimensions shown in the Drawings. The underlying subgrade shall be
compacted sufficiently to assure that no distortion will occur with the
placement of the limerock base.
B. Transporting Limerock: The limerock shall be transported to the point
where it is to be used, over rock previously placed if practicable, and
dumped on the end of the preceding spread. No hauling over the
subgrade or dumping on the subgrade shall be done.
C. Spreading Limerock:
1 . The limerock shall be spread uniformly, and all segregated areas
of fine or coarse rock shall be removed and replaced with
well-graded rock.
2. When the specified compacted thickness of the base is greater
than 8-inches, the base shall be constructed in two courses. The
1 1/12/98 LIMEROCK BASE 02232-2
thickness of the first course shall be approximately one-half the
total thickness of the finished base, or enough additional to bear
the weight of the construction equipment without disturbing the
subgrade.
D. Compacting and Finishing Base:
1 . General:
a. For single course base, prior to spreading, the specific
section requiring base shall be scarified and then shaped
so as to produce the required grade and cross section
after compaction.
b. For double course base, the first course shall be cleaned of
foreign material, bladed & brought to a surface cross
section approximately parallel to that of the finished base.
Prior to the spreading of material for the upper course, the
density tests for the lower course shall be made and the
County Engineer shall have determined that the required
compaction has been obtained. After the spreading of
material for the second course is completed, its surface
shall be finished & shaped so as to produce the required
grade & cross section after compaction and free of scabs
& laminations.
2. Moisture Content: When the material does not have the proper
moisture content to insure the required density, wetting or drying
will be required. If the material is deficient in moisture, water shall
be added and uniformly mixed in by discing the base course to
its full depth. If the material contains an excess of moisture, such
r ! excess shall be reduced or removed until the required moisture is
attained before being compacted. Wetting or drying operations
shall involve manipulation of the entire width and depth of the
base as a unit.
3. Density Requirements: As soon as proper conditions of moisture
are attained, the material shall be compacted to a density of not
less than that currently existing on the compacted surface.
U
4. Density Tests:
a. During final compacting operations, if blading of any areas
is necessary to obtain the true grade and cross section, the
compacting operations for such areas shall be completed
1 1/12/98 LIMEROCK BASE 02232-3
I �
prior to making the density determinations on the finished
base.
b. At least one density determination shall be made at each
location where limerock is placed on each day's final
operations on each course, & the density determinations
shall be made at more frequent intervals if deemed
necessary by the Engineer.
5. Correction of Defects:
a. If at any time the unsuitable material should become
mixed with the base course material, the Contractor shall
dig out and remove the mixture, reshape and compact
the subgrade and replace the materials removed with
clean base material, which shall be shaped and
compacted as specified above.
b. If cracks or checks appear in the base, either before or
after priming, which in the opinion of the Engineer would
impair the structural efficiency of the base course, the
Contractor shall remove such cracks or checks by
rescarifying, reshaping, adding base material where
necessary and recompacting.
E. Testing Surface: The finished surface of the base course shall be
sufficient so that when the asphalt surface course is applied, no
irregularities exist or appear after traffic is placed on the final surface.
All irregularities shall be corrected by scarifying & removing or adding
limerock as may be required, after which the entire area shall be
recompacted as specified herein before.
F. Thickness Determinations: The thickness of the compacted limerock
base shall vary to achieve the final elevations as shown on the plans.
G. Priming and Maintaining:
1 . The prime coat shall be applied only when the base meets the
specified density requirements and the moisture content in the
top half of the base does not exceed 90 percent of the optimum
- moisture content of the base material. At the time of priming, the
base shall be firm and unyielding.
2. The Contractor will be responsible for assuring that the true crown
and grade are maintained with no rutting or other distortion and
11/12/98 LIMEROCK BASE 02232-4
I
that the base meets all the requirements at the time the surface
course is applied.
