DESCRIPTION

1.1 Slide removal and slump repair shall include excavation, loading, hauling, placing and shaping of waste or replacement of materials.

a). Slide Repair - This work shall consist of the removal and disposal of any materials such as soil, rock and vegetation which has encroached onto the roadway and cannot be routinely handled by a motor-grader during ditch cleaning and surface-blading operations.

b). Slump Repair - This work shall consist of filling, with select-material, depressions or washouts in roadway which have developed and cannot be routinely filled by a motor-grader during surface-blading operations.

REQUIREMENTS

3.1 Slide removal and slump repair shall be performed whenever necessary during Purchaser's use to facilitate traffic, proper drainage, and to prevent resource damage.

3.2 Material removed from slides shall be placed at locations designated by the Forest Service. Unless otherwise agreed, material shall not be wasted over road-fills and material placed shall be shaped and compacted by the hauling and spreading equipment

3.3 When filling depressions or washouts, selected-material shall be moved from agreed locations, placed in layers and compacted to withstand settlement and deformation.

Existing aggregate-surfacing shall be salvaged when practicable and replaced after depressions have been filled.

Damaged aggregate-base and surfacing shall be repaired under Specification T-806, Surface Repair.

3.4 Following slide repair, roadway shall be shaped so as to reasonably conform to the adjacent roadway, unless otherwise agreed.

3.5 During repair, care shall be taken not to permanently foul aggregate or bituminous-surfaces through covering or mixing with earth or other debris from ditches, slides or other sources.

T-803 SURFACE-BLADING

DESCRIPTION

1.1 This work shall consist of maintaining a native or aggregate surface roadbed in a condition to facilitate traffic and provide proper drainage. It includes maintaining the crown or slope of traveled-way, shoulders, drainage-dips; all ditches, berms and turnouts, and provides a level of smoothness appropriate for the traffic served.

3.1 Surface-blading shall be performed immediately before, during and after the Purchaser's use as necessary and practicable to facilitate traffic and proper drainage.

3.2 The roadbed, including turnouts, shall be scarified if necessary and bladed to remove ruts and other irregularities and shaped. Existing aggregate-surface material shall be bladed to conserve material and to prevent segregation of particle sizes. While performing surface-blading during routine road-maintenance, Purchaser shall avoid permanently fouling surfaces through covering them with rocks, earth or debris from sideditches, slides, or other sources. Purchaser shall avoid blading surface material off of the roadbed.

3.3 When directed by the Forest Service, residual bituminous material from previous surface-stabilization treatments shall be scarified and reduced to produce material not exceeding three-inches (76.2 mm) in greatest dimension.

3.4 Cut-slopes or designed berms shall not be undercut.

3.5 At intersections, the roadbeds of side-roads shall be graded for a reasonable distance to assure proper blending of the two riding-surfaces.

3.6 All ditches shall be cleaned and maintained to latest constructed cross-sections to provide free-drainage.

Drainage-dips shall be maintained to conform to details shown in the drawings.

3.7 Designed berms shall be repaired when necessary by placing selected-material. Other berms, which are determined by the Forest Service as not necessary, shall be removed.

T-806 SURFACE REPAIR DESCRIPTION

1.1 This work shall consist of repairing potholes or small soft areas on imported aggregate surface, paved surface or native surfaced roads when materials are inadequate to withstand continuing use.

1.2 This work includes preparing the area to be repaired, furnishing and placing all necessary materials, and other work necessary to repair the surface.

MATERIAL

2.1 Aggregates - The types and gradations of aggregate shall be similar to, and compatible with, the existing surface material, as determined by the Forest Service.

a). Pit-run Aggregate: Pit-run aggregates shall consist of native materials of a size and gradation that can be taken directly from the source and placed on the road without crushing or screening. The maximum size shall be three-inches in the greatest dimension.

b). Grid-rolled Aggregate: Grid-rolled aggregate shall consist of native materials of a quality that can be taken directly from the source, without crushing or screening, and broken-down on the road by grid-rolling. The material shall be broken-down to a maximum size of three-inches (76.2 mm) in the greatest dimension.

c). Crushed Aggregate: Crushed-aggregate shall be crushed stone, slag, or gravel meeting current Forest

Service or State DOT requirements.

2.2 Material used in the repair of bituminous pavements may be acquired from local commercial sources. If a mixing table is required, the location shall be approved by the Forest Service. The bituminous mixture to be used by the Purchaser shall be approved by the Forest Service. The Purchaser's share of the quantity of bituminous mixture used in the appraisal estimate will be shown on Road Maintenance Plan. However, Purchaser's share of the work may vary depending on Purchaser's hauling schedule, ground conditions, other traffic, etc.

2.3 Water, if required, will be as specified in Supplemental Specification T-803-1. Water source locations are shown on the timber sale area map.

2.4 Borrow material used in the repair of soft areas may be from Commercial or Forest Service sources as agreed to with the Forest Service. The quality and quantity of the material used in the repair will be limited to that needed to provide a stable traveled way for hauling.

T-806 SURFACE REPAIR (Cont.) REQUIREMENTS

3.1 Aggregate surface repair shall be performed as often as necessary during Purchaser's use to facilitate traffic and to prevent extensive damage to the road-surface.

3.2 Aggregate Surface Repair - Existing aggregate, which has been contaminated with unsuitable material from the subgrade or from other activities shall be removed as directed by the Forest Service. New aggregate shall be mixed until it is uniform throughout, at a moisture-content suitable to prevent segregation and to attain the desired compaction.

The aggregate shall be spread in a uniform layer, with no segregation of size, and to a loose depth that shall have the required thickness when compacted.

If the required compacted depth of any aggregate base or surface course exceeds six inches, it shall be placed in two or more layers of approximately equal thickness. The maximum compacted thickness of any layer shall not exceed six- inches.

Hauling equipment shall be operated over the surface at the previously constructed layer in such a way as to minimize rutting or uneven compaction.

Compaction and grid-rolling, if required, will be as specified in Supplemental Specifications; T-803-2 and T-

803-3 as applicable.

All material removed from aggregate-surface repair shall be disposed of as designated by the Forest Service.

3.3 Bituminous Pavement Repairs. The areas to receive bituminous pavement repairs will be marked on the road surface by the Forest Service just prior to Purchaser performing the work.

3.4 Potholes (deep patch). Surface Course and Base Course materials shall be excavated to a depth necessary to reach firm, suitable material. The minimum depth of excavation shall be 2 inches and the maximum depth of excavation shall be to the top of the subgrade.

The edges of the prepared hole shall be extended to form a vertical face in un-fractured asphalt surfacing.

The prepared hole shall generally be circular or rectangular in shape, dry, and cleaned of all loose Material.

Prepared potholes shall be patched or barricaded immediately.

The faces of the prepared hole shall be tacked with a slow-setting emulsified asphalt.
