Surveys conducted by the Alaska Department of Environmental Conservation (DEC) in 2007, 2010, 2011 and 2016 indicate that 90% of Alaskan communities report road dust as a problem (DEC 2018). The Federal Highway Administration (FHWA) (1998) estimates up to one inch of surface aggregate is lost on unpaved roads annually. That equates to 10 million tons of dust released into the atmosphere (EPA 2017). This poses health hazards, safety concerns, and environmental impacts along these roads, degrading the mobility of both people and goods to communities connected by such roads.
