(a) Intent.
(1) This ordinance intends to set out specifications and requirements for the repair, replacement, and restoration of asphalt over concrete or brick, asphalt concrete pavement, concrete pavement, resurfacing heel-ins, and sidewalk replacement as it relates to roads, streets, sidewalks, or drainage channels that need to be repaired, restored or replaced due to utility related infrastructure construction, repair, restoration, or replacement.
(b) Type A Pavement Trench - Asphalt Over Concrete Pavement or Asphalt Over Brick Pavement.
(1) Each concrete edge shall bear on twelve inches (12") minimum of undisturbed soil. If, during excavation of the trench, the removal of large rock results in a void within the twelve-inch (12") zone, the contractor shall fill the void with compacted backfill or compacted granular backfill (same as trench backfill specified).
(2) All concrete must be a minimum of three thousand (3,000) psi, six (6) bag mix, and air entrained.
(3) The asphalt-wearing course cap shall be installed when cold milling and full-width asphalt overlay are not to be provided. In areas where a full-width pavement overlay is specified, the contractor may, at their option, mill the existing pavement before trenching for the proposed sewer installation: provided that existing pavement protrusions (valve boxes, manholes. etc.) are provided with temporary asphalt around these protrusions to eliminate hazards to vehicles immediately following milling of the existing pavement. The asphalt-wearing course cap may be deleted if milling is performed before trenching. However, the asphalt-wearing course cap must be provided if the existing pavement is not milled before trenching. It shall be substituted with concrete during cold weather periods when hot mix asphalt is unavailable.
(4) All areas where the pavement has been removed during construction shall be restored in accordance with these details within thirty (30) calendar days following the pavement removal unless otherwise approved by the city. If it is determined that such restoration is not feasible within this time frame, the contractor shall install a temporary, hard, drivable, and maintainable surface (asphalt or concrete), which will be subject to the approval of the City.
(c) Type C Pavement Trench - Asphalt Concrete Pavement (Driveways and Parking Lots.
(1) Each edge of asphalt concrete shall bear on twelve inches (12") minimum of undisturbed soil. If, during the excavation of the trench, the removal of large rock results in a void within the twelve-inch (12") zone, the contractor shall fill the void with impacted backfill or compacted granular backfill (same as trench backfill specified).
(2) All areas where the pavement has been removed during construction shall be restored per these specifications within thirty (30) calendar days following the pavement removal unless otherwise approved by the city. If it is determined that such restoration is not feasible within this time frame, the contractor shall install a temporary, hard, drivable, and maintainable surface (asphalt or concrete), subject to the city's approval.
(d) Type E Pavement Trench - Concrete Pavement.
(1) Concrete pavement sections removed or impacted during excavation shall require the replacement of the entire length of the concrete slab from the edge of the road to the joint at the center of the roadway. No partial slabs of concrete are to remain.
(2) Each concrete edge shall bear on twelve inches (12") minimum of undisturbed soil. If, during excavation of the trench, the removal of large rock results in a void within the twelve-inch (12") zone, the contractor shall fill the void with compacted backfill or compacted granular backfill (same as trench backfill specified).
(3) All concrete must be at least three thousand (3,000) psi, six (6) bag mix, air-entrained.
(4) Final pavement replacement saw cuts before pavement restoration shall be perpendicular to the sides of the drives.
(5) All areas where the pavement has been removed during construction shall be restored per these specifications within thirty (30) calendar days following pavement removal unless otherwise approved by the city. If it is determined that such restoration is not feasible within this time frame, the contractor shall install a temporary, hard, drivable, and maintainable surface (asphalt or concrete) which shall be subject to the approval of the City.
(e) Cold Milling and Full-Width Asphalt Overlay.
(1) Overlay is to be placed utilizing a paving machine approved by the WV Department of Transportation (WVDOT).
(2) If the existing pavement is striped, striping must be replaced per WVDOT requirements.
(3) If cold milling of the concrete in the pavement restoration items is necessary, such concrete shall have cured at least twenty-eight (28) days before cold milling.
(4) Milling shall be performed per the current edition of the West Virginia Division of Highways Standard Specifications, Roads and Bridges. Section 415. Hot mix asphalt wearing course shall be per section 401. A tack coat shall be applied to the milled surface before placement of the overlay per item 408.
(5) Asphalt wearing course overlay shall have one and one-half inch (1 ½") thickness.
(6) Limits for pavement restoration with roadway shall be twenty (20) linear feet beyond the installation of any infrastructure.
(f) Sidewalk Replacement Details.
(1) Concrete sidewalk.
A. The following specifications shall be met:
1. Concrete - shall be three thousand five hundred (3,500) psi min., seven and one quarter (7 ¼) bag mix, air-entrained
2. WWF 6 x 6/10
3. Concrete shall be at least four (4") inches thick unless otherwise noted and six inches (6") thick where the walk crosses the driveway with a two-inch minimum thickness in either instance.
4. Tooled joints at four (4) feet o.c.
5. Expansion joints at twenty (20) feet o.c.
6. Four (4) inch aggregate base.
(2) Asphalt concrete.
A. The following minimum specifications shall be met:
1. Asphalt concrete shall be poured at a minimum of two inches (2") thick.
2. The base shall be a four (4") inch-thick aggregate base.
(3) Minimum thicknesses are shown for concrete and asphalt sidewalks. If actual thicknesses are greater, the contractor shall match the existing sidewalk thickness.
(4) For replacement of existing concrete removed during construction, if an existing control joint is located within two (2) feet of the edge of the disturbed area, the existing concrete shall be removed and replaced with the additional width to the existing control joint.
(g) Diagrams and Technical Drawings. Diagrams and technical drawings clarifying the above specifications are on file with the City of Vienna Public Works Department. They shall be consulted for clarification before any repair, restoration, or replacement work.
(h) Penalty. In addition to any civil remedy, including injunctive relief, civil damages, and the like, violation of this ordinance is a misdemeanor. It shall result in a fine through the Vienna Municipal Court of five hundred dollars ($500) per day per incident.
