August Newsletter
In this quarterly e-newsletter, you’ll find summaries and links to the latest technical news and best practices from the U.S. and around the world, highlighting applications of winter maintenance research and technology and the latest transportation research by state DOTs, universities, TRB and FHWA. See the newsletter.

Clear Roads Project Featured in Roads & Bridges Magazine
The environmental best practices manual developed through a recent Clear Roads project was featured in an article in the September 2015 issue of Roads & Bridges magazine. See the article.

Clear Roads TAC Meeting
The Clear Roads Technical Advisory Committee met April 12-14 in Rhode Island to select research projects for 2016 funding. Minutes will be posted soon 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

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.

Snowplow Lighting
Researchers developed a synthesis report of best practices for the use of snowplow lighting, including headlights, work lights and warning lights. The report looks at different lighting types and configurations, and provides recommendations for implementation.

New Resources

National Survey Compiles 2014-2015 Winter Maintenance Data
We published our first Annual Survey of State Winter Maintenance Data, which compiles winter resources, material and cost data from 35 states for the 2014-2015 winter season. The published spreadsheet includes all submitted data as well as calculated statistics and a United States map that graphically displays many of these metrics. A new round of data collection for the second year of the survey will begin this summer.

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

Winter Maintenance at TRB
Clear Roads compiles an annual overview of the winter maintenance papers presented at the Transportation Research Board Annual Meeting. The review includes abstracts, author contact information, and links to each paper. Read more.

Webinar Intro to Clear Roads
In December 2014, Clear Roads representatives presented to the Caltrans Division of Equipment about Clear Roads’ structure, resources and research. The purpose was to highlight the pooled fund’s activities related to winter maintenance equipment. See the recorded webinar.

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.
