Trench Detail.
Unless otherwise ordered by the Director of Public Works or his/her designee, typical trench detail specifics shall be
as follows:
A. All Paved City of Cody Streets.
1. The finish course of all paved streets will be cut out to a 5 foot minimum width, to be reviewed on
the site by the Director of Public Works or his/her designee and laid to a compacted depth one inch
deeper than the pavement being replaced, but not in any event less than three inches, with appropriate
paving equipment and utilizing a pavement machine in all instances in which pavement is required to
be placed for trenches or other excavations of any kind next to curb and gutter projects, except that, in
the case of small holes and short, narrow trenches, the Director of Public Works or his/her designee
may approve other procedures which, in his judgment, are sufficient to meet standards for compaction
and other specifications and requirements applying to street construction.
2. The asphalt to be used shall be ½” inch hot mix asphalt, as determined by the Director of Public
Works or his/her designee, compacted and contiguous with existing asphalt road.
B. Type A trenches 24” in depth and shallower
Trench must be filled from bottom to within 3” of finish grade with sand slurry containing:
Cement (0.45 sack/CY)
Water (39 Gallons/CY)
Coarse Aggregate (Size No. 57: 1700#/CY)
Sand (ASTM C-33; 1845 #/CY)
Type A trenches are exempt from compaction tests, leveling course and road base requirements. Sand
slurry, without the cement additive, if approved by the city is also an acceptable alternative.
Trenches 24”in depth and greater:
Materials used for bedding and backfill shall be carefully deposited in layers suitable to the
equipment used for compaction, wetted to optimum moisture content and compacted to at least
the density of ninety-five (95) percent compaction. The layers are not to exceed twelve inches
(12) in depth. Materials used for backfill shall be free from ashes, cinders, refuse, clods, frozen
material, boulders (materials larger than 8” in the greatest dimension) or other materials that are
unsuitable. Sand slurry, without the cement additive, if approved by the city, is the preferred
method of backfill, but the alternative listed above is given for completeness.
C. The City Director of Public Works or his/her designee shall be notified and given the opportunity of
inspection prior to the commencement of each stage of construction.
D. Trench Details for temporary patch, during times when hot mix is unavailable, are the same as indicated
above. Cold mix will be substituted for hot mix. All cold mix patches will be monitored by the Permittee
until spring when the cold patch is removed and a hot mix permanent patch can be made. Permittee is
responsible for both the temporary patch and the permanent repair unless approved otherwise, in writing,
by the Director of Public Works or his/her designee. Permittee is responsible for two years following
acceptance of the trench by the City of Cody.
E. All Permittees working within the City of Cody right-of-way agree by the filling out of the cut/excavation
permit to follow the standards for traffic control as outlined in the MUTCD standards manual. The
