T-800A PREFACE

The U.S. Department of Agriculture (USDA), Forest Service has developed these maintenance specifications (T-specs) for use with Provisions C5.31#.

T-800C DEFINITIONS

Wherever the following terms are used in the road maintenance specifications, the intent and meaning shall be interpreted as follows:

Base Course. Material used to reinforce subgrade or, as shown on drawings, placed on subgrade to distribute wheel loads.

Berm. Curb or dike constructed to prevent uncontrolled roadway runoff water from discharging onto fillslope.

Borrow. Material taken from designated borrow sites.

Crown, Inslope, and Outslope. The cross slope of the roadway which aids in drainage and traffic maneuverability.

Culvert. A conduit or passageway under a road, or trail.

Drainage Dip. A dip in the roadway which intercepts and diverts surface water runoff. A drainage dip does not block the movement of traffic.

Drainage Structure. A manufactured structure which controls the runoff of water from the Roadway including, but not limited to, overside drains, aprons, flumes, down drains, downpipes, and culverts.

Lead-off Ditch. A ditch used to transmit water from a drainage structure or drainage dip outlet to the natural drainage area.

Roadbed. The portion of a road between the intersection of subgrade and side slopes, excluding that portion of the ditch below subgrade.

Roadside. A term denoting the area adjoining the outer edge of the roadway.

Roadway. A term denoting the area consisting of the traveled way and shoulders.

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.

Slide. A concentrated deposit of soil, rock and other debris from the cut slope often extending onto

Fleetwood Stewardship IRSC Bighorn National Forest Page 4 of 15 Tongue Ranger District the roadway, whether caused by mass land movement or accumulated raveling.

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.

Fleetwood Stewardship IRSC Bighorn National Forest Page 5 of 15 Tongue Ranger District

Maintenance Specifications. Specifications which detail conditions and requirements peculiar to the individual project in addition to requirements identified in the national specifications.

Subgrade. Top surface of roadbed upon which subbase, base course, or surface course is constructed. For roads without subbase, base course or surface course, that portion of roadbed prepared as the finished roadway.

Traveled Way. That portion of roadway, excluding shoulders, used for the movement of traffic.

Turnouts. Short sections of traveled way constructed with additional width to allow for safe passing of traffic.

Water Source. A place designated in individual projects for acquiring water for road maintenance purposes.

T-802 VEGETATION REMOVAL – ROADSIDE

802.01 DESCRIPTION

Work consists of cutting and disposing of vegetation that reduces the operational capability of the road including compromised visibility of signing, gates, or approach railing on bridges. Work also includes vegetation removal for the purpose of restoring site distance to an acceptable level.

802.02 MAINTENANCE REQUIREMENTS

A. Vegetative matter shall be removed to a maximum height of 6 inches and a minimum of 5 feet outside of the roadway which reduces sight distance, impedes vehicular travel, or interferes with road maintenance operations such as surface blading, ditch and culvert cleaning, and bridge maintenance.

B. Low shrubs and brush which do not restrict sight distance, do not impede road maintenance, and reduce erosion need not be removed if the road surface can be adequately maintained without doing

so. This is not applicable to bridge sites.

C. For bridge sites, remove roadway vegetation within a minimum of 20 feet from abutments as measured along the center line of the road. Cut vegetation to provide a vertical clearance of 14 feet from the road and bridge surface elevation by trimming any encumbering tree limbs.

D. .Do not leave woody debris and slash or concentrations which may plug ditches or culverts, drainage channels, or on roadway.

T-805 ROAD GRADING

805.01 DESCRIPTION

Work consists of keeping a native or aggregate roadbed in a condition to facilitate traffic and provide proper drainage. It includes maintaining the crown, inslope, outslope or drainage dips of the traveled way; maintaining turnouts and shoulders; repairing berms; and blending approach road intersections.

805.02 MAINTENANCE REQUIREMENTS

A. Road grading shall be performed before, during, and after Purchaser's use as often as necessary to facilitate safe use and proper drainage.

B. Road Grading shall preserve the existing cross-section. Surface irregularities shall be eliminated and the surface left in a free-draining state and to a smoothness needed to facilitate traffic. On aggregate surfaced roads, thoroughly loosen surfacing material to no less than 2 inches depth or the depth of defects. Scarification to facilitate cutting to the full depth of potholes or corrugations may be elected but will be considered incidental to blading. Do not scarify to a depth that will cause contamination of the surfacing. Surface material which has been displaced to the shoulders or turnouts shall be returned to the traveled way. A grading pattern shall be established to retain surface material on the roadbed and to provide for a thorough mixing of the materials within the completed surface width.

C. Unless otherwise shown in Table T-805.1, compaction of traveled ways will be accomplished using Compaction Method A and will commence immediately following blading.

1) Compaction Method A: Adjust the moisture content of the material to a moisture content suitable for compaction. Fill the interstices around rock with earth or other fine material as practical. Operate hauling and spreading equipment uniformly over the full width of each layer until there is no visible evidence of further consolidation.

2) Compaction Method B: 7 to 10 ton pneumatic, steel, or equivalent vibratory roller, operated to cover the full width three times. Adjust the moisture content of the material to a moisture content suitable for compaction. Fill the interstices around rock with earth or other fine material as practical.

D. Smooth blading may be used as an interim measure on aggregate-surfaced roads to remove loose surfacing material from the wheel paths. Store removed materials in a recoverable windrow until blade processing as described above is feasible. Watering is not required for smooth blading. Accomplish smooth blading without distorting the existing cross-slope or crown of the traveled way.

E. Move and store loose surfacing materials on the high side of super-elevated curves and sections with uniform inslope or outslope. In crowned sections, store the material on either or both sides as elected. Windrow and place stored materials to provide not less than 12 feet of smooth traveled way on one-lane segments, or 20 feet of smooth traveled way on two-lane segments, or segments with turnouts. Place holes through windrows for drainage every 500 feet or less to provide drainage.

Fleetwood Stewardship IRSC Bighorn National Forest Page 10 of 15 Tongue Ranger District

F. Water, taken from water sources designated on sale area map, shall be applied during blading if sufficient moisture is not present to cut, mix, or compact the surface material.

G. On native surfaced roads, material generated under other maintenance specifications may be blended with the surface material being worked. On aggregate surfaced roads this material shall not be blended with surface or base course material unless agreed otherwise.

H. Roadway cut slopes or berms shall not be undercut, nor shall new berms be established unless agreed otherwise.

I. Berms shall be repaired by placing material, as needed to restore the berm, to reasonably blend with existing line, grade, and cross-section.

J. Drainage dips shall be cleaned and maintained to reasonably blend with existing line, grade, and cross-section. Lead-off ditches shall be maintained as in accordance with T-810.

K. Intersecting road junctions which are not closed or restricted from vehicular use shall be bladed to assure proper blending of the two riding surfaces.

L. 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.

Unless otherwise designated by Forest Service, the oversized material shall be removed and placed outside the roadway; do not obstruct drainage ways or structures. Placement into streams, lakes, or water courses will not be permitted.

M. Material resulting from work under this specification shall not remain on or in structures, such as culverts, overside drains, cattleguards, ditches, and drainage dips.

N. Material resulting from work under this specification, plus any accumulated debris, shall be removed from bridge decks and the deck drains opened.
