Clear Roads TAC Meeting
The Clear Roads Technical Advisory Committee met September 20-21 in Omaha, Nebraska, to select investigators for the 2016 research projects. Minutes will be posted on the Meetings page.

Clear Roads Featured in TR News
The January-February 2014 issue of TR News included an 8-page feature on Clear Roads and its research. The article discussed the impacts of completed and in-progress Clear Roads research, the value of interstate collaboration, and projects that Clear Roads is undertaking with other multi-state pooled funds. See the article.

Recent Research Results

GPS/AVL Guidance
Researchers developed an equipment guide that describes how winter maintenance agencies are currently using GPS/AVL technology. The guide serves as a resource for agencies that are looking to implement or expand their use of GPS/AVL.

Salt Best Management Practices
Researchers created a manual of road salt best management practices designed to help agencies increase efficiency and reduce costs in all phases of the salt usage process: procurement, storage and application.

Effectiveness of Agriculture-Based Deicers
Researchers tested deicers made from agricultural byproducts and complex chloride mineral (CCM) blends and developed a best practices manual for their use. The lab tests quantified the effectiveness of agriculture-based deicers at very low temperatures.

Benefits and Costs of Winter Maintenance Strategies
Researchers collected and synthesized information about the costs and benefits of several winter maintenance activities. They found that most practices, including plowing and the use of a wide range of deicing and anti-icing materials, had benefits that greatly exceeded their costs.

New Resources

National Survey Compiles Second Year of Winter Maintenance Data
We published our second Annual Survey of State Winter Maintenance Data, which compiles winter resources, material and cost data from 34 states for the 2015-2016 winter season. The spreadsheet includes all submitted data as well as calculated statistics and a United States map that displays many of these metrics. It also includes data from the 2014-2015 survey and displays averages and changes across the two-winter period.

Synthesis Report on Truck Washing Practices
A new Clear Roads synthesis report presents the results of a survey of state DOTs’ practices for washing snowplow trucks. The report focuses on best practices for using in-house wash bays, and also discusses alternatives such as off-site commercial washing facilities.

Webpages Showcase Clear Roads Magazine Articles, Videos
Our Feature Articles page highlights the media coverage Clear Roads has received in the last decade, including articles in national magazines like Roads & Bridges, APWA Reporter, Better Roads and TRB’s TR News. Our Videos page compiles all of our research project webinars and other Clear Roads videos.

Cost-Benefit Toolkit
This web-based toolkit takes the guesswork out of evaluating winter maintenance investments by facilitating cost-benefit analysis for 21 different winter maintenance materials, equipment and methods. There are also training materials and a user’s manual to get you started.
