Within the limits of bituminous concrete or bituminous treated roadways all trench openings shall be backfilled and compacted as required in the New Jersey Department of Transportation Standard Specifications for Road and Bridge Construction, 1983 or latest edition. The upper 12 inches of the trench shall receive a temporary repair of six inches of compacted Soil Aggregate Designation I-5 (Formerly Type 2 Class B road gravel) as defined in the above-listed specifications, topped with six inches of bituminous stabilized base course, (Mix I-2) as defined in the above-listed specifications.
The temporary pavement shall remain in place until any residual settlement takes place, which time shall not exceed four months. During this time, the permittee shall assure maintenance of the pavement surface level. Manholes, valve boxes or other physical utility obstructions, shall have feathered approaches not to exceed a 5% slope where necessary and pavement lining shall be restored by the permittee for adequate traffic control.
Final paving shall be as follows; The existing pavement shall be milled to a clean straight line approximately 12 inches away from each side of the existing disturbed pavement to a depth of two inches. Pavement to be milled in areas not accessible to the milling machine shall be removed by other equipment. Any pavement below the specified level of milling that becomes dislodged or delaminated prior to resurfacing shall be replaced with bituminous concrete prior to resurfacing. Milled area shall be swept clean. Prior to placement of the two inches of Bituminous Concrete Surface Course, the existing asphalt shall be prepared in accordance with NJDOT Standard Specifications. Tack coat or prime coat, as applicable, shall be applied in accordance with the applicable rates and application methods set forth in said specifications. Placement, finishing, compaction and construction of the two inches of Bituminous Concrete Surface Course FA-BC (Mix I-5) shall be performed in accordance with the requirements set forth in the NJDOT Standard Specifications.
For roads which have a moratorium still in effect and said disturbance is less than 10% of the road, final paving shall be as follows; The existing pavement shall be swept and dried. The entire trench area plus one foot border of the existing pavement to remain shall be heated with an infrared heater to a temperature between 320 - 350 degrees, without burning or oxidizing it. The heater shall be removed. The softened asphalt shall be scarified to a depth of two inches. Rake the rejuvenator into the softened asphalt. Place virgin Bituminous Concrete Type FA-BC (Mix I-5) into the trench area and mix with the existing asphalt. Level and compact the trench area.
For roads which have a moratorium still in effect and said disturbance is equal to or greater than 10% of the road, final paving shall consist of milling and paving two inches of the entire pavement surface from curb to curb, with Bituminous Concrete Type FA-BC (Mix I-5) as defined in the above-listed specifications. For applications associated with a building permit, said limits shall extend from property line to property line, for all other applications said limits shall extend a minimum of five feet beyond the disturbance, or a minimum of 25 feet, whichever is greater.
The applicant shall notify the Township Engineer at least two business days prior to the final restoration of trenches so that the adequate inspection can be arranged.
