[Amended 11-20-2017 by Ord. No. 20-2017]
The applicant to whom such permit is issued shall, within the time limited in such permit, replace the earth and pavement in the excavation in such manner as proscribed herein and the same shall be left in as good condition as it was before the excavation was commenced. Except as otherwise herein stated, all street work performed shall be in accordance with the applicable provisions of the New Jersey Department of Transportation Standard Specifications for Road and Bridge Construction, 2007, and as amended. Reference to articles or sections hereinafter refer to said state highway specifications.
A. Trenches shall be backfilled in layers not to exceed six inches and a vibratory tamper must be used. Ninety-five-percent compaction shall be required. Puddling of backfill is strictly prohibited. Should there be a deficiency, additional backfill material shall be supplied by the permittee. Whenever the City Engineer shall deem the material unsatisfactory for backfill, the permittee shall provide acceptable material for the backfill.
B. Roadways with a concrete base shall be restored using a combination of concrete and asphalt. The amount of concrete and asphalt to be used at each such excavation shall be as directed by the City Engineer. (See detail at end of chapter.)
C. Bituminous concrete street restoration specifications.
(1) Gravel. Gravel shall be installed six inches thick. The gravel shall consist of compact soil aggregate Type I-5. The use of a recycled asphalt product (RAP) or recycled concrete product may be substituted for the soil aggregate as long as it meets the New Jersey Department of Transportation (NJDOT) requirements for I-5 materials. The City Engineer may, at his discretion, submit samples of the soil aggregate for a gradation analysis, with the costs of said analysis borne by the applicant.
(2) Temporary roadway restoration.
(a) Less than 100 square feet.
[1] For openings in asphalt roadways that are less than 100 square feet, the temporary restoration will consist of the installation of six inches of soil aggregate, Type I-5, to a level of six inches below the level of adjacent paved surfaces. A four-inch lift of stabilized base course, Mix I-2, followed by a two-inch lift of a bituminous concrete cold patch shall be installed to grade.
[2] These temporary surfaces shall be in place for a period of not less than 45 days to allow sufficient settlement to occur. Should settlement continue to occur, the City Engineer shall determine when the work is acceptable for final restoration. The permittee shall be responsible for all maintenance deemed necessary by the City Engineer until such time as the final restoration is completed.
(b) Greater than 100 square feet.
[1] For openings in asphalt roadways that are greater than 100 square feet, the temporary restoration will consist of the installation of six inches of soil aggregate, Type I-5, to a level six inches below the level of the adjacent paved surfaces. A six-inch lift of stabilized base course, Mix I-2, shall then be installed to grade.
[2] These temporary surfaces shall be left in place for a period of not less than 45 days to allow sufficient settlement to occur. Should settlement continue to occur, the City Engineer shall determine when the work is acceptable for final restoration. The permittee shall be responsible for all maintenance deemed necessary by the City Engineer until such time as the final restoration is completed.
(3) Final roadway restoration.
(a) Newly paved streets.
[1] In the event that an emergency or hardship requires the opening of a roadway that has been resurfaced by the City during the previous five years pursuant to §
255-18, a full-width restoration will be required. The restoration will consist of six-inch dense graded aggregate base course, and a six-inch bituminous stabilized base course, Mix I-2, brought to existing grade, within the excavated area. A full width, curb to curb, milling two inches in depth to extend 20 feet beyond the limit of excavations will be performed after proper settlement in the trench area. The allowable time for the settlement shall be 45 days unless otherwise directed by the City Engineer. The final surface course shall be a two-inch bituminous concrete surface course, Mix I-5. (See detail at end of chapter.)
[2] Trench restoration may be permitted under special circumstances and at the option of the City of Pleasantville and City Engineer for openings having a minimum impact on the longevity and serviceability of the street in question. (See detail at end of chapter.)
(b) Streets paved between five and eight years prior to proposed opening.
[1] Any street opening on a street that has been constructed, reconstructed, or overlaid between five years and eight years after the completion of said construction, reconstruction, or overlay will require a half-width paving from the center line to the curb on the side affected by the opening. The trench shall be repaved with six inches of gravel or similar subbase, four-inch stabilized base (HMA 19M64) to the surface. The half width of the street shall then be milled 1 1/2 inches deep from the center line to the curbline a distance of 20 feet on either side of the opening edges. A one-and-one-half-inch surface course (HMA 9.5M64) shall be machine-placed and rolled as per New Jersey Department of Transportation Standard Specifications for Roads and Bridges, 2007, and as amended.
[2] If the opening crosses over the center line of the street, the above street repair shall be full-width restoration.
(c) Streets paved over eight years prior to proposed opening.
[1] Where 20% or more of the existing surface width and/or a distance parallel or longitudinal to the roadway center line of 25 feet or more has been disturbed, the permittee shall mill the entire pavement surface from edge to edge or curb to curb and the full length of the trench plus five feet each side at a minimum depth of two inches. All milling and disposal of millings shall be done in accordance with Division 400 of the NJDOT Standard Specifications. The permittee shall clean and sweep the milled surface and apply tack coat in preparation for immediate paving. The area will then be paved with two inches of HMA 9.5M64 surface course in accordance with Division 400 of the NJDOT Standard Specifications. The City will require that the terminal ends of the paving be keyed and cut vertical to provide a smooth transition to the existing asphalt surface. Feathering will not be allowed.
[2] Where less than 20% of the existing surface and a distance parallel or longitudinal to the roadway center line of less than 25 feet has been disturbed, the permittee shall sawcut the existing surface course two inches deep at a location 12 inches beyond the trench surface, and remove the existing pavement to the same depth. Pavement removal shall be done by milling or another method as approved by the City Engineer. The permittee shall clean and sweep the milled surface and apply tack coat in preparation for immediate paving. The area will then be paved with two inches of HMA 9.5M64 surface course in accordance with Division 400 of the NJDOT Standard Specifications. The Township will require that the terminal ends of the paving be keyed and cut vertical to provide a smooth transition to the existing asphalt surface. Feathering will not be allowed.
(d) Calculating age of street.
[1] The five-year period as articulated herein shall be calculated from December 31 of the year in which said road was constructed, reconstructed or overlaid and run five years thereafter. The end date of this five-year period is the beginning date of the five-year to eight-year period articulated herein.
[2] The eight-year period as articulated herein shall be calculated from December 31 of the year in which said road was constructed, reconstructed or overlaid and run eight years thereafter. The end date of this eight-year period is the end date of the five-year to eight-year period articulated herein.
(e) No surface water shall be entrapped or ponded on the resurfaced areas. If any ponding occurs, the permittee will be responsible for performing whatever remedial action is required by the City Engineer.
(4) If more than one excavation would be required within a fifty-foot length, a single trench must be used rather than the individual excavations. Final restoration will require the entire pavement surface from edge to edge or curb to curb and the full length of the trench plus five feet each side at a minimum depth of two inches. All edges shall be coated with an asphaltic tack coat prior to a two-inch lift of bituminous concrete surface course, Mix I-5, being placed to a level even with the existing road grade.
(5) In all cases where concrete has to be removed prior to any excavation, saw cut methods of removal shall be used. The restoration of the concrete shall be according to the following specifications:
(a) It shall be Class B with a design strength of 4,000 pounds per square inch (psi).
(b) It shall have a minimum thickness of not less than four inches for sidewalk, six inches for driveway aprons and eight inches for gutter.
(c) It shall have a minimum width of not less than five feet for sidewalks.
(d) It shall have control joints not more than five feet for sidewalk, 10 feet for curb and gutter and expansion joints and not more than 20 feet for sidewalk, curb and gutter.
D. By the acceptance of such a permit, the applicant shall be deemed to have agreed to comply with the terms hereof, and upon his failure to do so to pay on demand any cost or expense that the City may incur by reason of any shrinkage or settlement in the excavated area resulting from such excavation if such shrinkage or settlement shall occur within three months from the time the surface thereof is restored.
