The ERDC was tasked by the U.S. Marine Corps Systems Command to evaluate the new commercial dust palliatives for mitigating dust on helipads developed since the comprehensive testing performed by the ERDC in 2005. Both laboratory and field evaluations were performed on the dust palliatives. Laboratory evaluation consisted of observing the erosion and optical dust concentrations behaviors for three product application concentrations, 0.4, 0.8, and 1.2 gsy (gallons/square yard). Field evaluation of the dust consisted of constructing 150 ft by 150 ft helipads at the Marine Corps Air Station, Yuma, Arizona, and evaluating the ability of the dust palliatives to prevent dust and foreign object debris and compatibility with existing USMC dust abatement equipment. Approved products will be used to update the USMC Dust Control Handbook (PCN 50011240000). |
