3.1 Preparation for Dust-abatement Materials Other Than Water - Prior to application of any material, the entire roadbed shall be prepared as required under Specification T-803, Surface Blading.

Bituminous and other residue from previous treatments shall be scarified and pulverized to produce loosened material not exceeding three-inches in greatest dimension.

A light-application of water shall be applied just prior to applying the dust-palliative, unless otherwise agreed by the Forest Service.

3.2 Application Methods of Bituminous Dust-abatement Materials – One or more of the following methods shall be used as specified in C5.4, Table 2.

a). Direct Penetration -

1). Prepared Surface: The palliative application is made directly to the traveled-way and any shoulders prepared in accordance with Specification T-803. The road shall be closed to traffic until penetration is complete or until excess material is blotted according to Subsection 3.4, or as approved by the Forest Service.

2). No Surface Preparation: The palliative is applied directly to the existing surface, regardless of its condition. The road shall be closed to traffic until penetration is complete or until excess material is blotted according to Subsection 3.4, or as approved by the Forest Service.

b). Penetration - The top one-inch (25.4 mm) of roadway-surfacing is placed to the side in a windrow. The palliative application is made to the exposed roadway, and the windrow is pulled-back across the road as a blotter since penetration into the compacted-surface is minimal.

c). Enhanced Penetration - The top one-inch (25.4 mm), plus or minus, is loosened and left in-place. The palliative application then penetrates the loose material.

3.3 Weather Limitations - Dust-abatement materials shall not be applied when it is raining, when the surface is too wet to receive the material, or if rain is anticipated to occur within twenty-four-hours of palliative application.

Dust palliatives shall be applied only when the surface temperature of the traveled-way is fifty-degrees Fahrenheit in the shade, and rising.

3.4 Blotter Material - Blotter-material, when used, shall be spread in sufficient quantities to prevent tire pickup.

3.5 Traffic - Traffic shall be maintained in accordance with C6.33
