The final paving shall be installed when occupancy
permits have been issued for 70% of the properties in the subdivision
or when greater than 20% of the available properties have occupancy
permits and three years have elapsed since approval of the final plat,
whichever comes first. The asphalt binder is required after the first
year regardless of lot occupancy.
[2]
In the event that less than 20% of the land
is developed, and three years have elapsed since the approval of the
final plat, the Town Board may require final paving of the road in
conformance with this subsection. The developer shall then be required
to construct the road in conformance with all Town ordinances and
resolutions.
[a]
The Developer shall guarantee the improvements under this subsection for a period of three years from the date of final acceptance by the Town Board. This guarantee shall include total and complete restoration of any disturbed surface or component of the improvement to the standard provided in the construction documents per § 275-45 and ordinance specifications.

consist of cutting and disposing of trees, brush, stumps, roots, shrubs,
fallen trees, fence posts, fence wire, vines and other vegetation
and debris occurring within the project limits and disposing of the
same as required for the specified construction.
(a)
Method.
[1]
The clearing limits shall be the limits of the
right-of-way or easement unless otherwise stated or indicated on the
approved plans.
[2]
The contractor shall use whatever methods for
clearing and grubbing best suited to the site of work and which will
not cause damage to adjacent property.
[3]
The contractor shall remove obstructions, such
as street signs, small culverts and end walls, advertising signs and

and/or developer shall be responsible for the protection and replacement,
if necessary, of survey monuments which may exist throughout the project
area. Any disturbed survey monuments shall be replaced by a registered
surveyor at the contractor's expense.
(3)
Fine grading/excavation.
(a)
Prior to construction, the contractor shall
strip all topsoil from the right-of-way and stockpile. The entire
street right-of-way shall be excavated to the typical sections shown.[2] There will be areas where existing ground elevations and
proposed street grades will dictate that slope intercepts extend beyond
the right-of-way lines. The contractor shall construct low existing
elevations to proper right-of-way elevations. Existing elevations
that are higher in terrain may be left higher than typical. However,
excessive elevation differences in right-of-way from one side of the
street cross- section to the other will not be acceptable.
[2]
Editor's Note: The typical road section diagrams
are included at the end of the chapter.
(b)
The subgrade shall be comprised of sound nonorganic
material free from topsoil or other deleterious material. Acceptable
excavated subgrade material shall be moved to locations on this project
where fill is required.
(c)
The contractor shall proof roll (loaded truck)
the subgrade for the engineer in conjunction with the compaction testing
and prior to placing crushed stone base course. Subgrade in ditch
areas shall be excavated and graded to allow for the addition of a
minimum of four inches of topsoil.
(d)
Any excess material not needed for road construction
shall be hauled off site or placed and leveled in locations determined
by the engineer.
(4)
Embankments. Embankments consist of placing in embankments
and in miscellaneous backfills material obtained from roadway excavation
or borrow areas, all in accordance with these specifications and in
reasonably close conformity with the lines, grades, thicknesses and
typical cross sections shown on the approved plans.
(a)
Materials.
[1]
Materials for embankment shall consist of approved
materials and shall contain no logs, stumps, brush or other organic
material. Unsuitable material or frozen lumps shall not be permitted
to be placed in the embankment except in the area beyond the limits
of an assumed one-to-one slope extending outward from the outer limits
of the roadway shoulder line.
[2]
Materials to be in the top 12 inches of the
embankment shall be free of large stones, concrete and other materials
which would significantly affect scarifying, compacting and finishing
the subgrade.
(b)
Construction methods.
[1]
Before placing any material in an embankment,
the contractor shall clear and grub and also strip the topsoil. Unless
otherwise specified in the contract, the construction of embankments
shall be discontinued in the fall or early winter when weather conditions
prevail which will cause substantial freezing of the materials as
they are placed in the embankment, except when the materials used
are from rock excavation or are granular and contain only minor quantities
of silt, clay, loam or similar materials.
[2]
The material placed in an embankment shall be
placed in layers starting at the lowest elevation. The layers shall
be spread evenly to a uniform thickness throughout and parallel to
finished grade. The thickness of the layer shall be as necessary to
secure the required compaction, generally not exceeding eight inches.
Where it is not practical to place the material in layers eight inches
thick, such as marshes, wet ground, filling in water, or on a steep
hill side, a single layer may be constructed to a thickness not greater
than necessary to support the hauling equipment while placing subsequent
layers.
[3]
Embankments placed in wet marshes or swamps
shall in general be constructed by end dumping the fill material.
When marshes are excavated in a dry condition, the embankment shall
be constructed in layers and compacted so far as practicable. For
a description of the method, please refer to Section 203, Marsh Excavation.[3]
[3]
Editor's Note: See Section 203 of the "Standard
Specifications."
[4]
Where material placed for embankment consists
of rack or broken stone of sufficient size that placing in eight-inch
layers is not practical, the material may be placed in layers not
exceeding the average diameter of the largest pieces, provided there
will be no nesting and all the voids are filled with smaller stones
and satisfactory soil or rock fines.
(5)
Preparation of subgrade.
(a)
The contractor shall notify Martenson &
Eisele, Inc. after the completion of the subgrade construction. The
Town of Winneconne's surveyor/engineer will check and document the
subgrade elevations.
(b)
The contractor shall ensure that the subgrade
elevations are within the Town of Winneconnes tolerances (0.08 inch)
prior to notifying the Town of Winneconne's surveyor/engineer to verify
elevations.
(6)
Excavation below subgrade.
(b)
Excavation below subgrade (undercutting) may
be necessary over some portions of this project. If such excavation
is required, the contractor shall obtain prior authorization from
the Engineer.
(c)
The contractor shall backfill excavations below
subgrade (two inches over-dig) with suitable on-site material. This
backfill material shall be compacted and brought up to the subgrade
elevations as shown on the typical sections[5] and shall be paid at the unit price supplied on the proposal
form.
[5]
Editor's Note: The typical road section diagrams
are included at the end of the chapter.
(7)
Compaction.
(a)
Except as otherwise provided, all fill placed
in embankments, all backfills in marshes and construction of rock
fills shall be compacted in accordance with requirements for standard
compaction unless special compaction is called for on the approved
plans or supplemental specifications.
(b)
The material to be compacted shall be at the
optimum moisture content to insure proper compaction. If the moisture
content is excessive in that excessive distortion or displacement
occurs under the compaction equipment, the material shall be allowed
too dry. Drying may be accelerated by aeration or manipulation by
means of blade graders, discs, or other appropriate equipment. If
the material is too dry to compact properly, water shall be added
in quantities deemed necessary to aid and accelerate effective compaction.
(c)
Each layer of an embankment shall be compacted
to the degree that no further appreciable consolidation is evidenced
under the action of the compaction equipment. No material shall be
placed for the succeeding layer until the required compaction is attained
for each layer.
(d)
The compaction shall be attained by specialized
compaction equipment, supplemented by hauling and leveling equipment
traveling with an equal distribution over each layer. If the compaction
attained through the hauling and leveling equipment is satisfactory
and sufficient, specialized compaction equipment will not be required.
If specialized equipment is necessary, specialized compaction equipment
shall include tamping rollers, pneumatic-tire rollers, vibratory rollers
or other types of equipment designed for compaction which will achieve
the desired result.
(e)
Tamping rollers shall exert a weight of not
less than 150 pounds per square inch of tamping surface. Other rollers,
such as pneumatic-tire roller, shall exert a weight of not less than
150 pounds per linear inch of roller width.
(f)
Embankments of six feet or less in height shall
be compacted to at least 95% of maximum density for their full depth.
Embankments over six feet in height shall have the top six feet compacted
to not less than 95% of maximum density, and those portions more than
six feet below the finished subgrade shall be compacted to at least
90% of maximum density. The maximum density of the fill material will
be determined in accordance with ASTM test designation D-1557, modified
Proctor test, and the relative density shall be determined in accordance
with the standard method of test for density for soil-in-place by
the Sand Cone Method, AASHTO Test Designation T 191, or other approved
methods. If such tests are required by the Town Board, they shall
be done at the developer's expense.
(8)
Compaction testing.

Subgrade.
[1]
The Town will contract with an independent testing
laboratory to provide the required testing services.
[2]
Testing will determine maximum density and optimum
moisture content for compaction in accordance with ASTM D1-1557 (one
test for each type of material for each source). Field density testing
will be conducted in accordance with ASTM D1-1556 and/or D-2922 and
D-3017. Minimum frequency for field testing shall be two acceptable
tests per roadway or as follows, whichever number is greater: one
moisture/density test per 100 feet of roadway.
(b)
Stone base.
[1]
The Town will contract with an independent testing
laboratory to provide the required compaction testing services.
[2]
The contractor shall compact each layer of aggregate
after placed and spread to the required thickness, width and section.
If the material is deficient in moisture content, to attain the required
density, the contractor shall add the necessary moisture during compaction
operations by means which provides a uniform application. Each layer
or course placed shall be compacted to at least 95% of the maximum
dry density as determined by the modified Proctor test (ASTM D1557).
Areas where proper compaction is not obtainable due to segregation
of materials, excess fines or other deficiencies shall be reworked
or removed and replaced with material that will yield the desired
results. The contractor shall shape and maintain the material to the
proper dimensions prior to and during compaction operations.
