5.8

EXECUTION

1. The contractor shall contact the West Virginia One-Call System (811 or 1-800-245-4848) at least two business days prior to an excavation. The contractor shall also contact the COR at least two businesses days prior to an excavation. The COR will provide the location for underground utilities within the project area owned by the Academy.

2. Subgrade Preparation: Excavate subgrade to the required depth. The exposed subgrade should be free of surface water. When practical, proof roll subgrade with a loaded dump truck or similar equipment approved by the COR. Perform proof rolling in the presence of the COR. Undercut rutting or pumping material as directed by the COR and replace with base material. After compaction, the subgrade shall not exhibit surface deviations for pavement areas greater than ½-inch when tested with a 12-foot straightedge applied both parallel and at right angles to the centerline of the area.

3. Fabric for separation: Engineering fabric shall be installed for separation between the subgrade and base course for the full pavement area. The fabric should be relatively smooth, free of sharp protrusions, depressions, creases, or debris. The joining of fabrics shall be accomplished by sewing (either in the field by portable sewing machine or during manufacture of the fabric) and shall be installed so any splice joints have a minimum overlap of 2 feet, or as directed by the COR. Construction equipment is permitted on the fabric provided all damage is repaired in accordance with Section 715.11.3 of the WV DOH Standard Specifications.

4. Crushed Aggregate Base Course: The compacted base course shall be 12 inches thick and constructed in accordance with WV DOH Standard Specification 307. The maximum compacted lift thickness shall be 6 inches. Tailgating is not permitted. Each layer shall be thoroughly and uniformly compacted by rolling. The moisture content shall be maintained at a level sufficient to facilitate compaction. No base course shall be placed when the subgrade is frozen or when it is sufficiently wet that the surface can be marred by construction equipment.

5. HMA base and wearing courses: The compacted lift thickness of the HMA base course shall be 2.5 inches. The compacted lift thickness of the HMA wearing course shall be 1.5 inches. Immediately before placing the hot mix asphalt, clean the underlying course of dust and debris. The HMA shall be struck off in a uniform layer of such depth that, when the work is completed, it will have the required thickness and conform to the grade indicated. Regulate the speed of the paver to eliminate pulling and tearing of the asphalt mat. After placing each lift, the mixture shall be thoroughly and uniformly compacted by rolling. Compact the surface as soon as possible without causing displacement, cracking or shoving. The sequence of rolling operations and the type of rollers used shall be at the discretion of the Contractor. The speed of the roller shall, and at all times, be sufficiently slow to avoid displacement of the hot mixture and to be effective in compaction. Any displacement occurring as a result of reversing the direction of the roller, or from any other cause, shall be corrected at once. Continue rolling until the surface is of uniform texture and true to grade. To prevent adhesion of the mixture to the roller, keep the wheels properly moistened. However, excessive water will not be permitted. In areas not accessible to the roller, the mixture shall be thoroughly compacted with hand tampers. Any mixture that becomes loose and broken, mixed with dirt, contains check-cracking, or is in any way defective shall be removed full depth, replaced with fresh HMA, and immediately compacted to conform to the surrounding area. This work shall be done at the Contractor’s expense. Skin patching will not be allowed. Construction methods shall be in accordance with applicable Sections 401 and 405 of the WV DOH Standard Specifications, unless otherwise noted.

6. Joints: Key-in the existing and new HMA pavement joint for the all locations where the new pavement abuts the existing HMA pavement. The width of the key shall be 24 inches and taper from a depth of 1.5 inches at the interface of the new pavement to 0 inches within the existing pavement. The milling technique shall not cause damage to any part of the existing pavement structure that is not to be removed. A tack coat shall be applied to all joints.

7. Pavement Markings: Pavement markings consisting of a 4-inch wide solid white line shall be used to delineate the existing roadway and the widened pavement area. A 4-inch wide solid white line shall be applied for full length around the remaining perimeter of the widened pavement area. The total length of solid white line marking is approximately 475 linear feet. Pavement markings consisting of 4-inch wide broken white line shall be used to delineate the new pavement area into two 10-foot wide lanes, as directed by the COR. The broken line shall consist of 3-foot line segments and 6-foot gaps, and shall begin and terminate at the taper zones of the new pavement area. The total length of the broken white line marking is approximately 190 linear feet, including line segments and gaps.

8. Drainage: An earthen drainage channel shall be constructed a minimum of 1 foot away from the new pavement area, parallel to the lane orientation. The channel shall have 2H:1V side slopes and be a minimum of 1 foot deep. The channel shall provide drainage from the southern end of the new pavement area and continue around the perimeter of the asphalt. The depth should be increased as necessary to provide positive drainage toward the existing inlet basin located approximately 25 feet north of the project area.

9. Seeding and mulching: All disturbed areas and the earthen channel shall be seeded and mulched with Kentucky 31 fescue. Any area failing to establish a stand shall be re-seeded, re-fertilized and re-mulched as directed by the COR.

10. Disposal: Dispose of debris, rubbish, scrap, and other non-salvageable materials resulting from the paving operations with all applicable federal, state, and local regulations. Storage of waste materials on the project site is prohibited. Transport all waste materials resulting from the project from Government property for legal disposal, except waste soil. Waste soil excavated from the pavement area shall be stockpiled on the Academy property as directed by the COR.
