412.04 Weater Limitations All dust abatement materials shall be applied only when the surface to be treated contains appropriate moisture to get adequate penetration and absorption of dust abatement materials. Application during a light rain is acceptable provided the material penetrates the road surface, and does not flow to low areas or off the road surface.

R01-85 SPS 412-3 (1/95)

REGIONAL SPECIAL PROJECT SPECIFICATION

Tumbledown Road Reconstruction Chloride brines and Lignin materials shall be applied only when the temperature is 40oF or higher and the ground is not frozen.

To accelerate the penetration and absorption of calcium chloride flake materials, the road surface may be dampened prior to or after the flake application.

Clarified Dust Oil shall be applied only when the road surface and atmospheric temperature is 50oF or more and rising or above 60oF and falling.

412.05 Equipment The distribution equipment shall be so designed, equipped, maintained, and operated such that the dust abatement material may be applied uniformly on variable widths of surface. Application shall be at readily determined and controlled rates from 0.10 to 0.50 gallons per square yard with uniform pressure and application. The allowable variation from the specified application rate shall not exceed 10% of the specified rate for individual distributor loads, and 2% of the specified rate for the entire project.

For liquid products the following requirements shall apply: (1) The spray pattern from each nozzle on the spray bar shall be uniform across the spray bar; (2) Distribution equipment shall include accurate volume measuring devices or a calibrated tank, a thermometer for measuring temperatures of tank contents, and a hose and nozzle attachment for applying material to areas inaccessible to the spray bar.

Calcium Chloride Flake shall be spread with equipment that evenly distributes the material across the required road width. The weight of flake in distribution vehicles trucks shall be accurately determined prior to application. The relative weight of material placed shall be easily determined during application.

412.06 Preparation

of Road Surface One or more of the following preparation and application methods shall be followed as DESIGNATED IN THE SCHEDULE OF ITEMS.

Method 1. Apply the dust palliative directly to the previously prepared surface.

For Method 2 and 3 the road surface shall be processed by blading below the elevation of raveling, wash boarding, and pot holes. The top two inches of surfacing material shall have moisture content greater than 5 percent. After processing, the surface shall be shaped by blading to the required cross section SHOWN ON THE DRAWINGS. The prepared surface shall be approved in writing by the Engineer prior to treatment.

R01-85 SPS 412-4 (1/95)

REGIONAL SPECIAL PROJECT SPECIFICATION

Tumbledown Road Reconstruction Method 2. A layer of loose cushion material approximately 1 inch in depth shall be developed for the full width of traveled way and kept in as loose a condition as possible prior to applying dust palliative. After the dust palliative has penetrated and pickup of material will not occur, the surface shall be compacted as SHOWN ON THE DRAWINGS, or compacted over the full treated width with either roller(s) or loaded truck(s).

If the one-inch layer of cushion material becomes compacted by traffic prior to treatment, a one-inch thickness shall be cut from the surface and bladed into a berm on the shoulder. Just prior to applying the dust palliative, the material in the berm shall be bladed to a uniform depth across the full width of the previously watered surface. The loose material shall have a moisture content greater than 5 percent just prior to applying dust palliative. After application, compact as specified above.

Method 3. Approximately 1 inch of the surface material shall be bladed into a berm on the shoulder. The initial application shall then be made on the existing surface. As soon as practical, but no more than 1 hour after application, the material in the berm(s) shall be bladed to a uniform depth across the previously treated surface and watered, if necessary, to meet the 5 percent minimum moisture content. The second application shall then be applied. Compaction shall be performed as specified in Method 2.

412.07 Application Dust palliative application rates and width of road surface to be covered shall be as of Dust SHOWN ON THE DRAWINGS. For liquid products the rate is expressed as gallons Palliative per square yard and for Calcium Chloride Flake, the rate is expressed in pounds per square yard. If the actual application rate is less than specified, the dust abatement material left over will be applied at locations and application rates designated by the Engineer. If the application rate used by the contractor is greater than specified and additional material is required to complete the project coverage, the additional material shall be furnished and applied at the Contractor's expense.

The Engineer may field test Chloride brines and Lignin materials prior to application to make sure that the products meet the minimum concentrations specified. Acceptance of the material will be based on the concentration shown on the manufacturer's certificate, or on results of laboratory quality assurance tests done by the Forest Service on samples taken from distribution or hauling vehicles.

Uniform distribution shall be obtained at all points. For liquid products the spray pattern from each nozzle on the spray bar shall be uniform across the spray bar. For flake products, the coverage will be uniform on the road surface. Overlapping or skipping between spread sections shall be corrected. Accidental spillage and area with excess dust palliative that are hazardous to traffic shall be covered with additional road surfacing material at the contractor's expense. The surface of adjacent structures

R01-85 SPS 412-5 (1/95)

REGIONAL SPECIAL PROJECT SPECIFICATION

Tumbledown Road Reconstruction and trees shall be protected from spattering or marring. Dust palliative material shall be discharged only in approved areas, and shall not be allowed to flow into ditches or stream courses.

412.08 Maintenance & Opening Traffic The treated road surface shall be open to traffic within two hours following treatment.

Traffic control and the prevention of vehicle undercoating is the contractor's responsibility. If dust abatement material is picked up by vehicles, the contractor shall apply road surfacing blotter material, and if necessary apply more dust abatement material to repair the damage. No compensation will be made for blotter or the additional dust abatement material to correct these problems. Reductions in payment may be made where traffic control and repair of the treated surface are not adequate.

Lignin Pay Factor = 1.0 - (48% - % Concentration Applied)

(24%) If laboratory quality assurance tests on Clarified Dust Oil indicate that the maximum limits for viscosities, or asphaltenes were exceeded, the Forest Service may reduce payment by multiplying the lowest pay factor as determined below, times the contract unit price for Item 412(05) or Item 412(06), times the accepted quantity.

Original Kinematic Viscosity Pay Factor = 100/Original Viscosity Asphaltene Pay Factor = (5 percent)/(percent Asphaltenes) Residue Viscosity Pay Factor = 400/Residue Viscosity When each hauling/distribution vehicle cannot be readily weighed to determine quantities, the actual weight of material in full vehicles shall be determined at the start of the project. Thereafter, the number of vehicle loads applied to the road surface can be used for quantity determination, provided each load is full, each load is completely emptied on the project, and material lost from the load is deducted. The Engineer may direct the additional check weighing of loaded and empty vehicles at any time.
