All work done pursuant to the provisions of this article
shall be inspected by the Township.

The costs for establishing such lines and grades shall be paid by
the subdivider.
G.
All adjacent structures and areas disturbed or damaged
during street or road construction shall be properly repaired by the
party causing said damage.
H.
In the case where the Township finds that the ground condition and/or rock condition beneath a street provides sufficient stability so that part or all of the subbase requirements may be waived, modified or changed and still comply with generally recognized, sound engineering principles after appropriate tests have been taken, subbase requirements may be so waived, modified or changed by the Township, in accordance with § 186-38 of this article.
All trees, roots, stumps, brush, down timber,
rotten wood, rubbish and any other objectionable material shall be
removed from the site and shall include the removal of any obstruction
interfering with the proposed road construction for the full right-of-way
width, or as approved by the Township.
A.
Subgrade shall be prepared to accommodate the placement
of the pavement structure and shoulders or gutters in accordance with
PennDOT specifications and within reasonably close conformity to the
lines, grades and widths shown on the drawings and cross sections
or otherwise directed.
B.
Subgrade shall be graded to the elevation and cross-section
required with suitable soil or granule material compacted to the required
density.
C.
In cases where the required density or stability cannot
be obtained, the material in the area shall be excavated to a depth
that when replaced and recompacted at a moisture content not exceeding
optimum, the subgrade will have the required stability.
D.
The subgrade shall be properly prepared to receive
the subbase.
Where the surface of an existing nonskid roadway
conforms approximately to the proposed subgrade elevation, or where
an embankment less than nine inches in depth is to be made over such
roadway, the surface of the old roadway shall be scarified to a depth
of not less than four inches, to permit satisfactory reshaping, binding
and compaction of the subgrade.
A.
Base courses shall consist of one or more layers of
materials conforming to the requirements of one or more of the following
sections of PennDOT Publication 408, latest revisions.
(1)
Section 305, Bituminous concrete base course.
(2)
Notwithstanding any provisions of this article, a
special base course design may be approved by the Township Engineer,
provided the design provides a structural number equal to or greater
than the appropriate base course listed in the attached Minimum Street
Construction Standards.[1] Special complete roadway designs may also be submitted
for approval by the Township, with due cause other than financial
savings, provided the design provides a structural number equal to
or greater than the minimum structural number listed in the minimum
street construction standards chart.

coat applied as may be required for base course placement according
to Publication 408, latest revision.
D.
Base course(s) shall be properly prepared and a tack
coat applied as may be required to receive subsequent courses in accordance
with directions from engineer.
E.
A binder course shall be applied where required in
accordance with Table 1 or Publication 408, latest revision.
A.
Bituminous pavements shall consist of one or more
courses of bituminous mixture constructed on the prepared foundation
