Deicer Research Highlighted by TRB

The most recent issue of the national Transportation Research Board Newsletter has featured an article on a WTI research report sponsored by the Minnesota Department of Transportation.  “Field Usage of Alternative Deicers for Snow and Ice Control” summarizes non-chloride based deicers available on the market, including acetate, formate, glycol, and succinate based deicing products. The report explores the deicers’ feasibility for use as alternatives to chloride based deicers, and identifies next steps to determine if a non-chloride based deicer is a viable option for implementation in winter maintenance operations by MnDOT and local snow and ice removal providers. TRB and MnDOT have posted a link to the report. You can also read about the project here.

 

Corrosion of metals exposed to 25% magnesium chloride solution and tensile stress: Field and laboratory studies.

Researchers from WTI’s Winter Maintenance program have published “Corrosion of metals exposed to 25% magnesium chloride solution and tensile stress: Field and laboratory studies.” This case study investigated the corrosive effects of chemicals used for snow and ice control operations, to better understand the potential impact on transportation infrastructure and motor vehicles.

Cold Climate Researchers and Students Exchange Ideas at Summer Workshop

On August 10-11, 2017, the Center for Environmentally Sustainable Transportation in Cold Climates (CESTiCC) hosted its annual summer workshop at Washington State University (WSU) in Pullman.  CESTiCC is a USDOT University Transportation Center, led by a consortium that includes the University of Alaska Fairbanks, Montana State University (WTI) and WSU.  The annual forum provides an opportunity for the Center to showcase its projects, and for researchers to exchange ideas on a variety of topics related to environmentally sustainable transportation issues, which spurs collaboration and new directions for upcoming research.

The workshop attracted participants from numerous western states

The presentations covered a broad range of topics related to transportation in cold climates, including the properties, durability and longevity of construction materials; winter maintenance practices and products; and impacts of transportation on water and air quality.  Laura Fay, WTI’s Winter Maintenance and Effect Program Manager, presented her research on “Lab Testing of Alternative Deicers and Estimation of Remaining Deicers on Pavement,” and WTI Research Scientist Matt Blank gave a presentation on “Sizing Hydraulic Structures in Cold Regions to Balance Fish Passage, Stream Function, and Operation and Maintenance Cost.”

Six graduate students were also invited to discuss their research in a student poster session and competition, providing an excellent professional development opportunity for young researchers. The second day of the event featured tours of the WSU lab facilities, and a field trip to the Kamiak Butte Park, a National Natural Landmark that boasts more than 150 bird, mammal, and vegetation species.

Students present their research and network with professional researchers at poster session

 

CESTICC Announces Summer Workshop

CESTICC Workshop Flyer Header

The Center for Environmentally Sustainable Transportation in Cold Climates (CESTiCC) will hold its annual Summer Workshop on Thursday, August 10 in Pullman, Washington at Washington State University. The workshop will provide an opportunity for exchange on each of CESTiCC’s research thrusts and will feature a student poster competition and lectern sessions on a variety of topics related to environmentally sustainable transportation issues and research. If you would like to submit an abstract for presentation or a poster title, please follow the instructions on the event’s flyer. Registration for this is event is free; all attendees and presenters should register online on the CESTiCC Workforce Development Page. For more information on the workshop, please click here. WTI hosted last year’s popular workshop in Bozeman; for questions, you can also contact Laura Fay.

Stateline Highlights Unpaved Roads Research

Stateline, a national website covering trends in state policy, published a feature story on a recent WTI project on the pros, cons, and costs of converting low-volume paved roads to unpaved roads. In “Dirt Roads Help Some Cities, Counties Drive Down Costs,” Stateline interviewed Principal Investigator Laura Fay about her research for the National Cooperative Highway Research Program, which sought to explore how commonly and under what conditions transportation agencies are converting paved roads to unpaved roads. Through a national survey, the project identified 48 agencies that have completed conversions, 70 conversion projects, and 550 miles of converted roadway. Click here to read the Stateline article.
