SECTION 9 TRENCH BACKFILL AND RESTORATION CONSTRUCTION REQUIREMENTS
1: Trench restoration shall be either by a patch or overlay method, as required and indicated on City of Renton

Specifications. An trenchin over four feet 4' in depth may use materials approved b the
4 -04 of the Standard y g () p y pp y
Engineer or Materials Lab for backfillirg below the four -foot (4) depth. If the existing material (or other material) Is
determined by the Engineer to be suitable for backfill, the contractor may use the native material, except that the
top six inches (6 ") shall be crushed surfacing top course material. The trench shall be Compacted to a minimum
ninety-five percent (95 %) density, as described in Section 2 -03 of the Standard Specfficafions. In the top six feet
(6) of any trench, backfill compaction shall be performed in eight to 12 -inch (8 -121 lifts. Any trench deeper than six
feet (61 may be compacted in 244nch lifts, up to the top six-foot (6) zone.
All compaction shall be performed by mechanical methods. The compaction tests may be performed in maximum
four -foot, (4') vertical increments. The test results shall be given to the Engineer for review and approval prior to
paving. The number and location of tests required shall be determined by the Engineer.
4. Temporary restoration of trenches for overnight use shall be accomplished by using MC mix (cold mix), Asphalt
Treated Base (ATB), or steel plates, as approved by the Engineer. ATB used for temporary restoration may be
dumped directly into the trench, bladed out and rolled. After Boiling, the trench must be filled flush. with asphalt to
provide a smooth riding surface. If the temporary restoration does not hold up, the Contractor shall repair the patch
within eight hours of being notified of the problem by the City. This requirement applies 24 hours per day, seven
