Abstract:

Dense airborne dust caused by military ground vehicles is a large, multi-faceted problem for the Department of Defense. One costly aspect of the problem is that fugitive dust and small rocks made airborne by ground vehicles on unpaved military service roads increases erosive damage to vehicle coatings. The dust palliative products most widely used to stabilize the surfaces of unpaved roads are formulated using corrosive salts such as magnesium chloride. These are effective at reducing erosive coating degradation but they negate that benefit due to their inherent corrosiveness of exposed metal on vehicle undercarriages. This report documents the testing, demonstration, and validation of several soil-binding materials that effectively suppress fugitive dust while being less corrosive than the most widely used dust palliatives. Based on laboratory and field test results, as well as data in the technical literature, a commercially available refined oil called Durasoil was found to be the most effective and least corrosive dust palliative of all materials and blends investigated. For purposes of calculating economic benefits, Durasoil was analyzed against magnesium chloride, which is the most widely used dust palliative. The projected return on investment of using Durasoil instead of magnesium chloride was 18.1.
