lumps and stone shavings of any dimension greater than two inches.
When pipe trenches are located beneath existing or paved roadway areas,
the trench shall be backfilled with PennDOT Specification 2A material
to the bottom of the existing or proposed base course as directed
by the Township Engineer. All backfill shall be thoroughly compacted
under the haunches and along the sides with mechanical tampers or
other approved methods as fast as placed up to a level above the top
of the pipe. The filling and tamping of the backfill shall be carried
up evenly on both sides of the pipe, care being taken not to raise
the pipe or move it off line during the operation.
(b)
The remainder of the trench shall then be filled and compacted
by tamping or rolling. The backfill material shall be evenly spread
in built-up layers not exceeding eight inches before tamping or power-rolling.
Care shall be taken that the material close to the bank, as well as
other portions of the trench, shall be thoroughly compacted.
(c)
Puddling or water flooding shall be restricted to consolidate
the backfilling of sandy or gravelly materials. No compacting shall
be done when the material is too wet to be compacted properly. If
this method is used, the first flooding shall be applied after the
backfilling has been compacted by tamping up to two feet above the
top of the pipes and the second flooding during or after the subsequent
filling of the trench. Any excess of water shall be avoided, in order
to prevent disturbances of the earth under and around the pipes, and
also to prevent an undue excess of pressure upon them.
(d)
Walking or working on the completed pipeline, except as may
be necessary in tamping or backfilling, shall not be permitted until
the trench has been backfilled to a height of at least 1 1/2
feet over the top of the pipes.
