I. 
Permanent restoration. Backfilling of any opening and/or excavations shall be as follows:
(1) 
Before completing the backfilling of any trench, a saw cut shall extend a minimum of 12 inches beyond the trench opening on all sides of the excavation.
(2) 
Initial backfill shall consist of a bed of 2B clean aggregate (AASHTO No. 57) six inches under the utility conduit extending to 12 inches above the top of the conduit.
(3) 
Final backfill:
(a) 
PADOT 2A (Township street) or 2RC (state road) coarse aggregate mechanically tamped in six-inch intervals to restoration depth; or
(b) 
Suitable excavated material backfilled by hand or by approved mechanical methods (new Township street only). Backfill shall be excavated material approved by the Engineer and containing no stones larger than four inches in maximum dimension. A maximum of 20% of the backfill volume may be stones if the stones are evenly distributed within the material. Excavated material shall be free of organic material, refuse, and frozen materials, subject to limitations specified, and shall be compacted in four inches loose lifts with mechanical tamper or eight inches loose lifts if vibratory equipment is used.
(4) 
Superpave 25.0 mm Base Course, extending a minimum of 12 inches on each side of the trench, shall be placed on top of the backfill. The improver shall be held responsible for any settlement within one year of the final restoration.

Superpave binder and wearing courses, properly compacted and graded to the surface of the street, shall be placed on top of the base course and sealed at the saw cut with an approved asphalt sealing material.
J. 
Temporary restoration. During winter construction periods, the trench shall be backfilled as in the first three items of the specifications for permanent restoration above. The final step shall be temporary application of bituminous stockpile mix to bring the trench to street grade. Inspection shall be made periodically to maintain the trench in condition satisfactory to the Township. On or before May 31 following the date the street cut was first made, the improver shall permanently restore the cut as in Subsection I(4) and (5) above.
