[Amended 1-18-2010 by Ord. No. 481[1]]
The street construction contractor shall perform all excavation,
protection, backfilling and maintenance necessary for completion of
work. The use of excavation machinery shall be permitted, except in
places where operation of same will cause damage to trees, buildings
or existing structures above or below ground; in that case, hand methods
shall be employed. Excavated material must be removed from the site
if reuse is not intended. If excavated material is intended to be
reused, it shall be piled so as not to encroach on private property,

Excavation shall consist of
removing all existing paving, concrete gutters, rock, base and soil
within the limits of work as specified on the drawings, to the required
depth necessary for preparing the subgrade. Unsuitable and surplus
materials shall be disposed of by the street construction contractor
beyond the limits of the project.
(2)
Excavation shall be in accordance
with PennDOT Publication 408, latest revision, Section 203, or any
superseding PennDOT publication on the same subject.

When the material encountered
at subgrade is determined to be unstable by the Township, it shall
be removed to a minimum depth of 12 inches below subgrade.
(2)
Class 4 geotextile fabric
shall then be placed over the earth in accordance with PennDOT Publication
408, Section 212, or any superseding PennDOT publication on the same
subject.
(3)
The geotextile shall extend
up and out of the unstable area for a minimum of two feet on all sides
of the undercut excavation.
(4)
3A modified aggregate will
then be placed over the geotextile up to subgrade level and compacted
in accordance with PennDOT Publication 408, Section 350, or any superseding

replaced and recompacted at a moisture content not exceeding optimum,
will have the required stability.
(3)
It shall be the responsibility
of the street construction contractor to protect and maintain the
subgrade at all times. In no case shall vehicles be permitted to travel
over the subgrade in a single track. The street construction contractor
shall promptly and satisfactorily reshape and recompact or remove

construct compacted 1.5-inch wearing course. Seal all joints, curb
face and gutter line, inlets, manholes, utility boxes and other structures
abutting the wearing course. Threshold ambient air and surface temperature
for applying the final wearing course shall be 35° F. and rising.

course to identify any defects, settlement, alligatoring or other
base failures requiring repair. Select base repair shall be performed
as follows:
[1]
As marked in the field
by the Director of Engineering and Codes, the street construction
contractor shall neatly saw cut or mill all areas to be excavated.
[2]
