SPECIFICATIONS

Activity Code 1090 - Road Reconditioning – 8 site (202T, 213, 220B, 274D, 229A, and 3 locations on

206 North) to receive approximately 660’ of Road Reconditioning. Blading operations to remove ruts, potholes, corrugations and unnecessary berms. Road Reconditioning includes reconditioning of leadoff ditches and other ditches within the reconditioning area.

All suitable dislodged aggregate shall be smoothly spread over the entire traveled way to produce proper cross slope or crown. (1/4” to ½” per foot of width).

All suitable aggregate which has been worked onto road shoulders by traffic or maintenance activities shall be reclaimed onto the traveled way. A definite, continuous, and smooth line between aggregate surface and road shoulder shall be obtained. Grass, pine needle, or leaf litter to be evenly spread within the traveled way after sifting out the surface aggregate. Care shall be taken to assure proper surface drainage following this operation. Excessive amounts of grass or leaf litter containing aggregate may be placed in areas designated by the COR.

Berming of litter and litter balls containing aggregate along the road shoulder(s) will not be allowed.

The contractor shall make as many passes as necessary to assure that the aggregate is sifted out of the grass and leaf litter.

If erosion has removed gradable material to the extent that there is not sufficient material within 300 feet to provide the surface smoothness or cross-section specified, notify the Project Inspector prior to proceeding. The inspector or COR may allow a modified cross-section and/or surface smoothness that effectively utilizes available material. The Contractor will not be held responsible for substandard work that results from the lack of suitable material.

Undercutting of road surface at the shoulder will not be allowed.

Blading operations exercise caution to prevent material from falling into watercourses. It includes removing sand and/or debris from the weep holes on the bridge decks and depositing the removed material in a location along the roadway that will not allow it to enter waterways or stream courses.

Removal of any down trees, branches, or other obstacles in the traveled way or shoulders that interfere with the specified work are considered incidental to Road Reconditioning and shall be removed from the traveled way and shoulders. Disposal shall be on National Forest land unless otherwise agreed upon by

COR. Disposal shall not impede traveled way, shoulders, stream courses, or flow lines.

Roadway widths shall be maintained no wider than 20’. No wide blading will be allowed. Culverts damaged due to wide blading will be fixed at the Contractor’s expense. Dips and swales within the traveled way designed to control surface drainage shall be maintained.

Quality Standard

• Road bed is firm, smooth, and finished to the intended width and cross slope, including turnouts. Aggregate surface material (if present) is uniform depth. Surface is free of ruts, potholes, washes and washboarding.

• Road surface drains completely. Cross slope or crown is ¼” to ½” per foot of width or existing slope if steeper than ¾” per foot of width.

• Intersections are smoothly blended. No abrupt grade breaks.

• Ruts, potholes, washboards and wash outs are scarified to the bottom of the defect. No areas of high blading exist.

• No loose rocks larger than 3” in its largest dimension remain on the traveled way and shoulders.

• No debris, trash, or otherwise unsuitable material exists on the traveled way and shoulders.

• Leaves and pine needles generated from ditch(es), traveled way and shoulders are evenly spread over traveled way unless otherwise directed by the COR.

• Ditches shall be cleaned to a minimum depth of 1 foot (12”) below the edge of shoulder or to rock and the slope of the ditch from the road shoulder to the bottom of the ditch is 2:1 or flatter. Transitions to 18” and 24” culverts are smooth and transition from normal ditch depth to the invert of the culvert in 20’ +/- 5’. Ditch debris shall not be left piled at or around culvert entrances. In no case shall ditches deeper than 24” be cut with a grader blade.

• Ditches shall not allow water to stand, except where existing ground conditions prevent water to drain.

• Loose rocks that are impeding proper drainage, dirt, slough, debris and deposits are removed from the ditch, including foreslope and backslope. Additional tools may be necessary to clean ditches with depths greater than 12”.

Maintaining all ditches in their original location to the shape and grade required to ensure roadway drainage. Clean associated lead-off ditches.

All ditches shall be maintained in their original location to the shape and grade required to ensure roadway drainage. Drainage structures and road appurtenances shall not be damaged during this operation. Handwork required to properly connect ditch flow to drainage structure inlets is considered a part of this activity. Cleaning lead-off ditches to drain is included in this item of work.

If erosion or other existing condition, has removed gradable material to the extent that the specified ditch depth or cross section cannot be maintained, notify the Project Inspector prior to proceeding. The inspector or COR may allow a modified cross-section and/or ditch depth that effectively utilizes available material. The Contractor will not be held responsible for substandard work that results from the lack of suitable material.

Unless otherwise directed all suitable material having the same character as the road surface excavated through ditch cleaning shall be reclaimed and used within the traveled way. Unsuitable material from ditches shall be spread along backslopes, in depressions, or on fill slopes in a manner which will not affect watercourses and drainage from the road surface. Unless otherwise directed, required to meet culvert inverts, or required to maintain positive flow of water, ditches shall be cleaned to a depth of 1 foot (12”) below the shoulder of the road and the slope of the ditch from the road shoulder to the bottom of the ditch is 2:1 or flatter. Deeper ditches may be required to maintain positive drainage or to match culvert entrances. No debris from ditches shall remain in or around culvert entrances.

The contractor is responsible for locating all utilities before beginning work. Any handwork required to properly connect ditch flow lines to drainage structure inlets is considered a part of this activity.

Care shall be taken to prevent unsuitable material being pulled onto aggregate surfaces.

Tail and Furrow Ditches.

All such ditches shall be opened to provide proper drainage away from the roadway. No material excavated from these structures shall be reclaimed onto the roadbed, no material will be allowed to be piled at the tail of the furrow ditch, the material will be scattered. A crawler tractor with dozer blade may be required to properly open these ditches during periods of wet soil conditions, or to remove brush and small trees.

Removal of any down trees, branches, or other obstacles in the ditchline, traveled way or shoulders that interfere with the specified work are considered incidental to Cleaning and Reshaping Ditches and shall be removed from the ditch line. Disposal shall be on National Forest land unless otherwise agreed upon by COR. Disposal shall not impede the traveled way, shoulders, or stream courses.
