“…Additionally, these specimens were cured for 24 hr. In the previous laboratory testing by Rushing et al (2007), increasing the cure time from 1 hr to 48 hr decreased the surface erosion for 0.2 and 0.4 gsy specimens. More cure time may be required for Durasoil ® so that the surface particles can bind effectively to withstand the air impingement testing.…”

“…The test method used in this study was developed during previous dust abatement evaluations at ERDC and refined during the last round of testing, which occurred from June 2005 to February 2006. A complete description of the testing apparatus, protocols, and history can be found in previous testing reports (Tingle et al 2004;Rushing et al 2007).…”

The U.S. Army Engineer Research and Development Center (ERDC) was tasked by the U.S. Marine Corps Systems Command (USMC) to evaluate commercial dust palliatives that have become available since the comprehensive testing performed on helipads by the ERDC in 2005. Both laboratory and field evaluations were performed on the dust palliatives. Laboratory evaluations consisted of observing erosion measurements and optical dust concentration for three product application concentrations, 0.4, 0.8, and 1.2 gsy (gallons/square yard). Field evaluation consisted of constructing 150-ft by 150-ft helipads at Marine Corps Air Station, Yuma, AZ. Evaluation of the dust palliatives was based on their ability to prevent dust and foreign object debris as well as their compatibility with existing USMC dust abatement equipment. Approved products will be used to update the USMC Dust Abatement Handbook (PCN 50011240000).

Effect of near-surface hydrology on soil strength and mobility

History has repeatedly demonstrated the potentially negative influence of near-surface hydrology on military mobility. Increased moisture and saturation in soil results in a transition from solid to somewhat liquid states. As soil approaches the liquid state, the shear strength available for supporting traffic of ground vehicles or aircraft diminishes. Historical engagements elucidate the importance for armies to recognize soil conditions that could compromise manoeuvre. Since World War II, the US Army has pursued research aimed at equipping soldiers with the tools and knowledge needed to account for the impact of near-surface hydrology on mobility. Significant portions of the research have been focused on characterizing soil trafficability as a controlling factor in ground vehicle mobility and on developing methods for rapidly assessing soil conditions to ensure adequate bearing capacity for expediently constructed roads and airfields. In contrast, hydrological conditions can also produce extremely dry soil with potential for surface layers to break down under ground vehicle and aircraft traffic loadings, resulting in a propensity for extreme dust generation, an entirely different problem for military mobility that the research has also been addressing. Mobility problems associated with these adverse soil conditions have not been eliminated, but the research has produced significant advancements.
