T-800-1

SPECIFICATION T-800 DEFINITIONS

Wherever the following terms or pronouns are used, 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.

800-1.5—Borrow—Select Material taken from designated borrow sites.

800-1.6—Clearing Limits—The limits of clearing as designated on the ground or on the drawings.

800-1.7—Crown, Inslope, and Outslope—The cross slope of the Traveled Way to aid in drainage and traffic maneuverability.

800-1.8—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.

800-1.9—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.

800-1.10—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—Dust Abatement Plan—A table which lists the road, dust palliative, application rates, and estimated number of subsequent applications.

800-1.12—Lead-off Ditches—A ditch used to transmit water from a Drainage Structure or Drainage Dip outlet to the natural drainage area.

800-1.13 —Material—Any substances specified for use in the performance of the work.

800-1.14—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 in Section H.21 of the contract/solicitation or National Forest resources and hauling can be done safely. This work will be shown in the above Road Maintenance Requirements.

Pre-haul Maintenance work the Contractor elects to perform will be in compliance with the Road Maintenance T- Specifications.

800-1.16—Roadbed—The portion of a road between the intersection of Subgrade and sideslopes, excluding that portion of the ditch below Subgrade.

800-1.17—Road Maintenance Requirements—A table which shows applicable road maintenance specifications to be performed by Contractor on specific roads.

800-1.18—Roadside—A general term denoting the area adjoining the outer edge of the Roadway.

800-1.19—Roadway—The portion of a road within the limits of excavation and embankment.

800-1.20—Shoulder—That portion of Roadway contiguous with Traveled Way for accommodation of stopped vehicles, for emergency use, and lateral support of base and Surface Course, if any.

800-1.21—Slide—A concentrated deposit of Materials from above or on backslope extending onto the Traveled Way or Shoulders, whether caused by mass land movements or accumulated ravelling.

800-1.22—Slough—Material eroded from the backslope which partially or completely blocks the ditch, but does not encroach on the Traveled Way so as to block passage of traffic.

800-1.23—Slump—A localized portion of the Roadbed which has slipped or otherwise become lower than that of the adjacent Roadbed and constitutes a hazard to traffic.

800-1.24—Special Project Specifications—Specifications which detail conditions and requirements peculiar to the individual project.

800-1.25—Subgrade—Top surface of Roadbed upon which Base Course or Surface Course is constructed. For roads without Base Course or Surface Course, that portion of Roadbed prepared as the finished wearing surface.

800-1.26—Surface Course—The Material placed on Base Course or Subgrade primarily to resist abrasion and the effects of climate. Surface Course may be referred to as surfacing.

800-1.27—Surface Treatment Plan—A table which lists the roads and surface treatments to be applied.

800-1.28—Traveled Way—That portion of Roadway, excluding Shoulders, used for the movement of vehicles.

800-1.29—Turnouts—That portion of the Traveled Way constructed as additional width on single lane roads to allow for safe passing of vehicles.

800-1.30—Water Source—A place designated on the Road Maintenance Map for acquiring water for road maintenance purposes.

800-1.31—Waterbar—A dip in the Roadbed which intercepts surface runoff and diverts the water off the Roadway.

3.7—Intersecting roads shall be bladed for a distance of 50 feet to assure proper blending of the two riding surfaces.

3.8 —Rocks or other Material remaining on the Traveled Way after the final pass that are larger than 4 inches in diameter or are larger than the maximum size of imported surfacing shall be removed from the Traveled Way.
