Specifications include, but are not limited to:All trenches and excavations shall be backfilled immediately after the installation of improved bedding. Trench backfill, beginning twelve inches (12") above the top of the pipe shall be as described herein, unless shown otherwise on the plans and/or directed by the Engineer. Trenches under pavement: Trenches under existing or proposed pavement shall be sand backfilled and consolidated by flushing. Excavated material may only be used for backfill material if determined suitable by the Engineer. Backfill material to be flushed shall be placed in six-foot (6') maximum lifts when the trench is within alley or street right-of-way, and in twelve-foot (12') maximum lifts when the trench is outside of alley or street right-of-way. Each lift shall be thoroughly consolidated by using water jets and vibrators. Consolidation of backfill by flushing and vibrating shall result in a final density which equals or exceeds ninety-five percent (95%) of the standard Proctor density. Water shall be applied so that effective settlement is obtained with a minimum amount of water (optimum moisture content). Trenches shall not be permitted to overflow. Special care must be taken during backfilling, flushing, and compacting operations to prevent pipe from floating. Water shall be introduced into the layer being flushed through a long pipe nozzle and in such a manner that the granular fill, tamped material or the previously placed layer will not be disturbed. The top one foot (1') of trenches shall be earth backfill compacted to a density equal to or greater than the existing adjacent undisturbed material or 95% of standard Proctor density.
