SECTION 200 - PERFORMANCE STANDARDS

ACTIVITY CODE: 210 - BLADING ROADS

BLADING AGGREGATE SURFACED ROADS

Maintenance Requirements

210.01(A) - Blading operations are to be done over the entire riding surface in order to remove, by cutting out, all ruts, potholes, corrugations and berms. All suitable dislodged aggregate shall be smoothly redistributed over the entire riding surface to produce the proper cross slope or crown at 1/4” to ½” per foot, or as specified. Road structural terms are illustrated on Typical Section drawings attached.

Traveled way surfaces may be insloped (toward the cut slope), outsloped (toward the embankment), or crowned (highest point near or at the road center sloping to both sides).

Elimination of all ruts, potholes, corrugations and berms. These defects shall be repaired by scarifying or cutting to the bottom of such defects to provide for uniform compaction of roadbed material. High grading, or any method which merely fills depressions with loose material, does not eliminate the defect or provide for uniform compaction and is therefore not acceptable.

Large rock or organic material removed from drainage facilities during cleaning process shall not be used as fill.

Existing drainage dips shall be cleaned and the outslope grade restored to equal or exceed the gradient of the road.

Sections of roads constructed with a roadside ditch shall be bladed and reshaped to maintain crown at centerline of the roadbed, or insloped except on curves where crown is omitted. Road cross sections shall slope uniformly both ways from crown apex to shoulders at a minimum blade of 2 percent and a maximum blade of 6 percent.

210.02(A) - Aggregate surfacing which has been worked onto road shoulders by traffic maintenance activities are to be reclaimed and smoothly redistributed over the entire riding surface. Riding surface widths are to be perpetuated as existing. Dips and swales designated to control surface drainage are to be maintained. No undercutting of road surface nor material berms will be allowed. Assure proper road crowns and surface drainage after all operations.

At the conclusion of the grading and shaping operations the roadbed shall be smoothed and dressed to produce a uniform grade and cross section and a surface free of hollows, depressions, and projections above the adjacent roadbed surface. No berm or ridge greater than 1” of any material shall be left along either shoulder of the roadbed unless directed by the Contracting Officer or designated representative.

210.03(A) - Usual amounts of grass, leaf litter or pine straw is to be smoothly spread within the riding surface after sufficient movement to sift out surface aggregate. Where grass, leaf litter or pine straw is excessive, as determined by the COR, this material will be piled in spots along the road shoulder and left to decay. Care must be taken to insure this material does not interfere with surface drainage nor present a safety hazard. Any such material is to be reclaimed in subsequent bladings and smoothly spread within the riding surface.

210.04(A) - Blading operations are to be conducted as required to remove surface material and accumulated debris from bridge decks. Care is to be exercised to not damage any part of the bridge. All material shall be smoothly redistributed over the riding surface at the bridge approaches.

210.05(A) - Loose rocks protruding three inches or more above the graded surface will be removed. It is permissible to waste these rocks off the riding surface but away from ditch lines.

210.06(A) – Lead off and wing ditches are to be cleaned and reshaped to provide drainage away from the roadway and are incidental to the blading operations. Material excavated from these ditches is not to be reclaimed onto the roadway.

210.07(A) Lead off and wing ditches, designated by the Contracting Officer, are to be cleaned and reshaped to provide drainage away from the roadway. Material excavated from these ditches is not to be reclaimed onto the roadway.

Lead off and wing ditches will be measured if they extend over 100 feet and will be measured as ½ of a tenth of a mile, otherwise each designated lead off or wing ditch will be considered to be incidental to the pay item.

Soil Moisture Conditions

210.10(A) - Suitable moisture conditions for surface blading shall be from 10 - 15 percent by weight. Unless authorized by the COR, no surface blading shall be performed while moisture content is outside this range. If conditions are too dry, the Contractor may provide water to increase moisture content at their own expense. It will be at the Government option to authorize additional water to increase moisture content using under Activity Activity Code: 260 - Dust Abatement when blading is considered critical and is placed on the individual task order. If moisture conditions are too dry or wet, the Contractor will not be required to meet the requirements of prosecution of work under section F.

BLADING NATIVE SURFACED ROADS

Maintenance Requirements

210.01(B) Blading operations are to be done over the entire riding surface in order to remove, by cutting out, ruts, potholes, corrugations and berms. All suitable dislodged material shall be smoothly redistributed over the entire traveled way to produce proper cross slope or crown at 1/4” to ½” per foot, or as specified.

Traveled way surfaces may be insloped (toward the cut slope), outsloped (toward the embankment), or crowned (highest point near or at the road center sloping to both sides).

210.02(B) Elimination of all ruts, potholes, corrugations and berms. These defects shall be repaired by scarifying or cutting to the bottom of such defects to provide for uniform compaction of roadbed material. High grading, or any method which merely fills depressions with loose material, does not eliminate the defect or provide for uniform compaction and is therefore not acceptable.

210.03(B) Large rock or organic material removed from drainage facilities during cleaning process shall not be used as fill.

210.04(B) Existing drainage dips shall be cleaned and the outslope grade restored to equal or exceed the gradient of the road. Sections of roads constructed with a roadside ditch shall be bladed and reshaped to maintain crown at centerline of the roadbed, or insloped except on curves where crown is omitted. Road cross sections shall slope uniformly both ways from crown apex to shoulders at a minimum blade of 2 percent and a maximum blade of 6 percent.

ROAD SURFACE MAINTENANCE – UTILIZING “SMOOTHING” (DRAGGING)

210.01(C) The surface or the road is smoothed by dragging using enough pressure on the blade to smooth the surface and drag excess material across the surface.

210.02(C) Surface maintenance operations are to be done over the entire riding surface in order to remove ruts, potholes, corrugations and berms. All suitable dislodged material shall be smoothly redistributed over the entire traveled way to produce proper cross slope or crown at 1/4” to ½” per foot, or as specified.

210.03(C) Large rock or organic material removed from drainage facilities during cleaning process shall not be used as fill.

210.04(C) Existing drainage dips shall be cleaned and the outslope grade restored to equal or exceed the gradient of the road. Sections of roads constructed with a roadside ditch shall be bladed and reshaped to maintain crown at centerline of the roadbed, or insloped except on curves where crown is omitted. Road cross sections shall slope uniformly both ways from crown apex to shoulders at a minimum blade of 2 percent and a maximum blade of 6 percent.

Method of Measurement

Measurement shall be made to the nearest tenth of a mile using an odometer calibrated over a measured mile.
