Diminishing dust in rural 有料盒子视频
Controlling dust from rural 有料盒子视频 roads and runways is a priority at the 有料盒子视频 University Transportation Center.
University of 有料盒子视频 Fairbanks transportation engineers have spent years working to clean up one of rural 有料盒子视频鈥檚 dirtiest problems.
Billowing clouds of dust, generated by the gravel roads and runways that connect most villages, have become an unfortunate part of life in those communities. Over time, that adds up to a huge problem: A lightly traveled 2-mile stretch of unpaved road can produce nearly 11,000 pounds of dust each month.
Those airborne particles create grime, hazardous driving conditions and, most critically, health problems for people who live amid the dust. The 有料盒子视频 University Transportation Center, which is part of 有料盒子视频鈥檚 Institute of Northern Engineering, has made the issue a priority since the mid-2000s, when the health implications of dust pollutants became clearer.
鈥淒ust is a huge problem in the villages,鈥 said AUTC Director Billy Connor. 鈥淚t鈥檚 really something we鈥檝e spent a lot of time working on.鈥
That fixation on dust has driven studies on several things 鈥 road design, speed limits and the characteristics of various 有料盒子视频 soils. Researchers have tested numerous additives, from plain old water to polymer stabilizers, to see what works best. AUTC even developed an ATV-mounted instrument to better measure dust levels at remote study sites and launched a pilot program in the Interior 有料盒子视频 community of Ruby.
That unorthodox focus by 有料盒子视频 researchers is helping 有料盒子视频 transportation officials understand what tools work best in their long-running battle with dust.
