ILLUSTRATION OF ROAD STRUCTURE TERMS
SPECIFICATION T-803 SURFACE BLADING
DESCRIPTION:
1.1—Surface blading is keeping a native or aggregate Roadbed in a condition to facilitate traffic and provide proper drainage. It includes maintaining the Crown, Inslope or Outslope of the Traveled Way, Turnouts, and Shoulder; repairing Berms; blending approach road intersections; and cleaning bridge decks, Drainage Dips, and Lead-off Ditches.
REQUIREMENTS:
3.1—Surface blading shall be performed before, during, and after Contractor's use as often as necessary to facilitate traffic and proper drainage.
3.2—The surface blading 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. Surface Material which has been displaced to the Shoulders or Turnouts shall be returned to the Traveled Way. The blading operation shall be conducted to prevent the loss of surface Material and to provide for a thorough mixing of the Material being worked.
3.3—Water, taken from Water Sources designated on Contract Area Map shall be applied during blading if sufficient moisture is not present to cut, mix, or compact the surface Material.
3.4—On native surfaced roads, Material generated from backslope sloughing, and ditch cleaning 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.
3.5—Roadway backslopes or Berms shall not be undercut, nor shall new Berms be established unless agreed otherwise.
Berms shall be repaired by placing Material, as needed to restore the Berm, to reasonably blend with existing line, grade, and cross-section.
3.6—Drainage Dips and Lead-off Ditches shall be cleaned and maintained to reasonably blend with existing line, grade, and cross-section.
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. Unless otherwise designated by the Forest Service, the oversized Material shall be disposed of by sidecasting. Sidecasting into streams, lakes, or water courses will not be permitted.
3.9—Material resulting from work under this specification shall not remain on or in structures, such as Culverts, overside drains, cattleguards, ditches, Drainage Dips, and the like.
3.10—Material resulting from work under this specification, plus any other accumulated debris, shall be removed from bridge decks and the deck drains opened. This includes existing debris under pre haul maintenance.
MEASUREMENT:
4.1—Surface blading will be measured to the nearest one-tenth (0.1) mile as measured by calibrated vehicle odometer along the road centerline.
SPECIFICATION T-806 DUST ABATEMENT
DESCRIPTION:
1.1—This work consists of preparing Traveled Way and furnishing and applying Materials to abate dust.
MATERIALS:
2.1—The roads requiring dust abatement, type of dust abatement Material to be used, the rates of application, and frequency of applications will be shown on Dust Abatement Plan. The Dust Abatement Plan may be changed by written Agreement.
2.2—Water. The locations of Water Sources are shown on Contract Area Map.
2.3—Dust abatement Materials shall meet the requirements of the following subsections of FP-14 Standard Specifications for Construction of Roads and Bridges on Federal Highway Projects.
| Emulsified Asphalt | 702.03 | |||
| Blotter Material | 703.13 | |||
| Magnesium or Calcium Chloride Brine | 725.02 | |||
| Calcium Chloride Flake | 725.02 | |||
| Lignin Sulfonate | 725.20 |
2.4—Testing of Materials. Certification of magnesium chloride, calcium chloride brine, calcium chloride flake, blotter material and lignin sulfonate will be provided by the manufacturer and approved by the Forest Service.
REQUIREMENTS:
3.1—General. Dust abatement Materials shall be applied to the road surface as necessary to control road surface loss, provide for road user safely, and minimize damage to adjacent resources.
3.2—Compaction. When the methods listed below specify compaction, Traveled Way shall be compacted by an 8 to 10 ton pneumatic, steel-wheeled or equivalent vibrating roller making 2 passes over the full Traveled Way and Shoulder width, unless compaction is not required on the Dust Abatement Plan.
3.3—Preparation to Dust Abatement Materials Other Than Water. The following applies to all methods of preparation.
Bituminous residue shall be scarified and pulverized to produce loosened Material not exceeding 4 inches in greatest dimension.
Traveled Way shall be bladed in accordance with T-803.
Prior to applying DO-6BA, DO-6PA, or DO-8, the top 2 inches of Traveled Way shall contain not less than 80 percent nor more than 120 percent of optimum moisture as determined by AASHTO T-99, Method C. Prior to applying other bituminous Material, Traveled Way shall have a moisture content between 1 and 3 percent. If surface dusting prevents the bituminous Material from penetrating, a light application of water shall be applied just prior to applying the bituminous Material.
Lignin Sulfonate and magnesium chloride shall be applied when the top 1 inch of Traveled Way contains not less than 3 percent moisture, nor more than 120 percent of optimum moisture as determined by AASHTO T-99, Method C.
Moisture content will be determined in accordance with AASHTO T-217 OR T-239.
One or more of the following methods shall be used, as specified in the Dust Abatement Plan.
Method 1: Compact Traveled Way and apply the dust abatement Material.
Method 2: Develop a layer of loose Material approximately 1 inch in depth for the full width of Traveled Way. Apply the dust abatement Material to this loose Material and compact after penetration. If traffic makes maintenance of the loose Material difficult, 1 inch of the Material may be bladed into a windrow along the Shoulder. The specified moisture content shall be maintained in the windrow and the top 1 inch of Traveled Way. The windrow shall be bladed to a uniform Material. When the dust abatement Material has penetrated, Traveled Way shall be compacted.
Method 3: Blade 1 inch of Material from Traveled Way into a windrow along the Shoulder. Maintain the specified moisture content in the windrow and the top inch of Traveled Way. Apply half the dust abatement Material. When the dust abatement Material has penetrated, the windrow shall be bladed to a uniform depth across dust abatement Traveled Way, and the remaining dust abatement Material shall be applied. Traveled Way shall be compacted.
Method 4: Develop a layer of loose Material approximately 2 inches in depth for the full width of Traveled Way. Apply half the dust abatement Material to the loose Material. Blade the top 2 inches into a windrow along the Shoulder. Apply the remaining dust abatement Material to Traveled Way and the Berm. Spread the Berm evenly across Traveled Way and compact.
3.4—Preparation for Dust Abatement with Water. Traveled Way shall be prepared in accordance with Specification T-803 Surface Blading when required.
3.5—Application Tolerance. Dust abatement Materials other than water shall be applied within 0.05 gallons per square yard of the rate specified.
3.6—Mixing Requirements. DO-6BA, DO-6PA, and DO-8 shall be thoroughly circulated in the distributor within 1 hour of application.
3.7—Weather Limitations. Dust abatement Materials shall not be applied when it is raining.
Bituminous Material shall be applied when the surface temperature of Traveled Way is 50 degrees Fahrenheit or higher.
Lignin sulfonate and magnesium chloride shall be applied when the atmospheric temperature is 40 degrees Fahrenheit or higher.
3.8—Blotter Material. Blotter Material shall be spread in a sufficient quantity to prevent tire pickup.
