Manholes, catch basins, and inlets shall be constructed

The brick and block shall be laid with broken joints,
and all vertical and horizontal joints shall be filled with 1:2 cement-sand
mortar. Straight joints shall be not more than 3/8 inch wide, and
radial joints not more than 1/2 inch in average width. The masonry
shall be carried to such a height that a mortar joint not more than
1/2 inch thick is needed for setting the head casting.
C.
No masonry shall be laid in water. Water shall not
be allowed to flow against or over masonry until it has had time to
set, as may be prescribed by the Borough Engineer.

Temporary pavements to carry traffic shall be
constructed at all points where the sewer crosses or runs through
a paved roadway. In placing the temporary pavement, the trench backfill
shall be compacted as directed up to within six inches of the surface,
after which the remaining six-inch space shall be filled with steam
cinders, which shall be well-rolled. The contractor shall maintain
this temporary pavement in a condition adequate for usual traffic
until such time as the Borough Engineer orders the permanent pavement
placed again. The cost of constructing and maintaining temporary pavements
shall be deemed included in the unit price bid per linear foot for
sewer construction.

All pavements disturbed by the sewer construction
shall be replaced by the contractor. In replacing pavements, the old

stone, as directed, to such a depth that after ultimate compression
it shall have a depth of five inches. Roll the stone to the satisfaction
of the Borough Engineer.

Apply bituminous binder grade OA-4 at the rate
of two gallons per square yard. This bitumen shall be applied from
a pressure distributor and shall have a temperature of between 300°
F. and 350° F.
(4)
Construct the Type A or Type T bituminous concrete
top, using material complying with the 1941 New Jersey State Highway

by the Borough Engineer, to produce a replaced section equal to the
old pavement which was removed.
D.
The cost of replacing all pavements shall be deemed
included in the unit price bid per linear foot for sewer construction.
