In this Clear Roads project, researchers developed metrics for comparing the two different forms of salt and conducted a variety of tests to measure their performance.
Real-time information about a pavement’s surface can help transportation agencies ensure roads have adequate traction and salt is applied only where it’s needed. This Clear Roads project evaluated roadway grip data as a viable source for informing winter maintenance operations, and developed models that use the data to identify the need for salt applications.
Clear Roads held its fall business meeting last month in Bloomington, Minnesota from September 16-18.
The Mechanical Rocker Test method, originally developed by Nebraska DOT more than a decade ago, was validated through Clear Roads research project 18-06 as a low-cost and repeatable method for determining the efficacy of liquid deicers. As a result of this work, all transportation agencies can objectively compare deicers on the market.
This recently completed Clear Roads synthesis project surveyed member states and other winter maintenance professionals and reviewed relevant literature to help transportation agencies implement effective policies and best practices for properly managing video and image data.
This new Clear Roads synthesis project surveyed maintenance professionals and reviewed published literature to identify opportunities in winter maintenance operations that could benefit from this emerging technology.
Clear Roads held its spring business meeting last month in Richmond, Virginia from April 15-17. Documents from the meeting, including the agenda, budget and minutes, are now available on the Clear Roads Meetings page.
To determine how well mixed salt products perform at lower temperatures, this Clear Roads project tested eight solids and prewet solids.
Agencies selecting a new or replacement storage system for their liquid deicers have a lot to consider, such as safety, environmental impacts, and cost-effectiveness. This Clear Roads project examined transportation and public works agencies’ systems and developed a manual of best practices for agencies to consult when creating a new system or expanding their current system.
This Clear Roads project examined the use of dashboards among transportation agencies to assess current strategies and identify innovative and effective practices. The results offer guidance to transportation agencies that are considering implementing or expanding their dashboard use to enhance winter maintenance operations.
