SPECIFICATION T-800 DEFINITIONS

Wherever the following terms or pronouns are used in Specifications T-801 through T-807, the intent and meaning shall be interpreted as follows:

800-1.1—Agreement. Maintenance projects require a mutually acceptable method to resolve the problems which arise when incompatible situations arise between drawings and specifications and actual conditions on the ground to allow orderly and satisfactory progress of the maintenance.

These specifications have been developed in anticipation of those problem areas and have provided that such changes will be by Agreement.

It is intended that drawings and specifications will govern unless "on-the-ground" conditions warrant otherwise, when specifications call for "Agreement", "agreed", or "approval" such Agreement or approval shall be promptly confirmed in writing.

800-1.2—Annual Road Maintenance Plan. A plan prepared by various users of one or several roads. The plan is an

Agreement on maintenance responsibilities to be performed for the coming year.

800-1.3—Base Course. Material used to reinforce Subgrade or, as shown on drawings, placed on Subgrade to distribute wheel loads.

800-1.4—Berm. Curb or dike constructed to prevent Roadway runoff water from discharging onto embankment slope.

800-1.6—Crown, Inslope, and Outslope. The cross slope of the Traveled Way to aid in drainage and traffic maneuverability.

800-1.7—Culverts. A conduit or passageway under a road, trail, or other obstruction. A culvert differs from a bridge in that it is usually entirely below the elevation of the Traveled Way.

800-1.8—Drainage Dip. A dip in the Traveled Way which intercepts surface runoff and diverts the water off the Traveled

Way. A Drainage Dip does not block the movement of traffic.

800-1.9—Drainage Structures. Manufactured structures which control the runoff of water from the Roadway including

Inslope, overside drains, aprons, flumes, downdrains, downpipes, culverts and the like.

800-1.11—Lead-off Ditches. A ditch used to transmit water from a Drainage Structure or Drainage Dip outlet to the natural drainage area.

800-1.12—Material. Any substances specified for use in the performance of the work.

800-1.13—Pre haul Maintenance. Road maintenance work which must be accomplished to maintain the roads to a satisfactory condition commensurate with the Contractor's use, provided Contractor's Operations do not damage improvements under FAR 52.236-9 or National Forest resources and hauling can be done safely. This work will be shown in the Annual Road Maintenance Plan as provided in 800-1.2.

800-1.14—Roadbed. The portion of a road between the intersection of Subgrade and sideslopes, excluding that portion of the ditch below Subgrade.

Slump repair is the filling of depressions or washouts in Roadway which cannot be routinely filled by a motor grader during

Surface Blading, T-803 Operations.

Slide removal and Slump repair includes excavation, loading, hauling, placing, and compacting of waste or replacement

Material and the development of disposal or borrow areas.

REQUIREMENTS

3.1—Slide Material, including soil, rock and vegetative matter which encroaches into the Roadway, shall be removed. The slope which generated the Slide Material shall be reshaped during the removal of the Slide Material with the excavation and loading equipment. Slide Material deposited on the fillslope and below the Traveled Way will not be removed unless needed for slope stability or to protect adjacent resources.

Surface and Base Courses shall not be excavated during Slide removal operations.

Slide Material which cannot be used for other beneficial purposes shall be disposed of at sites designated by the Forest

Service. Material placed in disposal sites will not require compaction unless shown on Road Maintenance Plan. Side casting may be approved by the Forest Service. Side casting into streams, lakes or water courses will not be permitted.

3.2—When filling Slumps or washouts, Material shall be moved from agreed locations or borrow sites, placed in layers, and compacted by operating the hauling and spreading equipment uniformly over the full width of each layer.

Existing aggregate surfacing shall be salvaged when practical and re-laid after depressions have been filled.

Damaged aggregate base, aggregate surfacing, and bituminous pavement shall be repaired under Specification T-804

Surfacing Repair.

The repaired areas of the Slump shall conform to the cross-section which existed prior to the Slump and shall blend with the adjacent undisturbed Traveled Way.

3.3—The maximum volume of Contractor responsibility for Slide and Slump repair is 10 Cubic yards per 100 foot station.
