Diminishing dust in rural 色视频下载
Controlling dust from rural 色视频下载 roads and runways is a priority at the 色视频下载 University Transportation Center.
University of 色视频下载 Fairbanks transportation engineers have spent years working to clean up one of rural 色视频下载色视频下载檚 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 色视频下载 University Transportation Center, which is part of UAF色视频下载檚 Institute of Northern Engineering, has made the issue a priority since the mid-2000s, when the health implications of dust pollutants became clearer.
色视频下载淒ust is a huge problem in the villages,色视频下载 said AUTC Director Billy Connor. 色视频下载淚t色视频下载檚 really something we色视频下载檝e spent a lot of time working on.色视频下载
That fixation on dust has driven studies on several things 色视频下载 road design, speed limits and the characteristics of various 色视频下载 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 色视频下载 community of Ruby.
That unorthodox focus by UAF researchers is helping 色视频下载 transportation officials understand what tools work best in their long-running battle with dust.
