Dense airborne dust caused by military ground vehicles is a large, multifaceted 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.

“…The test method developed for this evaluation was designed to provide a mechanism for rapidly screening multiple chemicals in various application scenarios in order to make inferences about performance. The testing protocol was a method developed by Rushing and Newman (2010), which was designed specifically for products intended for preventing dust generated by wind erosion.…”

Rhizobium tropici, a catalogued symbiotic nodulator of leguminous plants, is also known for its production of a gel-like extracellular polymeric substance (EPS). The natural functions of the biopolymer in the rhizosphere include surface adhesion, self-adhesion of cells into biofilms, formation of protective barriers, water retention around roots, and nutrient accumulation. We performed three treatability studies to evaluate the effectiveness of the biopolymer as a soil amendment to increase slope stability and reduce transport of solids in runoff water, reduce the transport of heavy metals associated with suspended sediment from small arms firing ranges, and reduce the generation of dust. Four soil types were used: Silty Sand (SM), Sandy Silt (ML), Silt (S), and Silty Clay (CL). These soil types were selected because they are prone to wind and water erosion thus presenting possible worst case scenarios. The study of sediment transport demonstrated that the biopolymer soil amendment was able to significantly reduce surface water erosion and particulate and heavy metal transport in leachate. The biopolymer soil amendment effectively maintained the slope stability of a simulated berm. In addition, biopolymer added to the Silty Sand soil at 0.5% (w:w) loading rate reduced dust production compared to the control at all relative humidities, indicating it should perform well in both arid and tropical environments.

Dust is an environmental, geotechnical, health, and economical hazard. Fugitive dust emanating along transportation systems such as roads, railways, and airports especially can have significant impacts on health, safety, material loss, cost of maintenance, and interfere with the facilities. Quantitative studies on the effectiveness of the proper dust palliatives and their environmental impact have been studied with a number of biological and chemical methods. The objective of this study was to establish a method for using the microbial Induced calcium carbonate precipitation (MICP) approach to reduce the percent of mass loss against erosive force of wind regarding to the concentration and characteristics of aggregate used, climate, and traffic amounts. The results of this study showed that the required precipitation for dust control of sand by 70% is less than 15 g CaCO/m between sand grains in bio-treated sand. The wind tunnel test results of this study also indicate that the effectiveness of the bio-treatment method for dust control depends on many variables, such as the percent of precipitated calcium carbonate and tensile strength.
