Understanding how chloride deicers move, disperse in, or migrate through different types of soils is critical to helping maintenance managers identify sensitive areas and adjust chloride applications to mitigate environmental impacts.
To help winter maintenance managers understand how sunlight affects melt rates, prioritize vegetation management, and communicate the benefits of roadside vegetation management to the public, this Clear Roads project produced a vegetation management guide.
This Clear Roads project developed a tool that states can use to quantify the economic value of their snow-and-ice programs.
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.
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.
Clear Roads project 20-06, Salt Shed Design Template, developed guidance for a set of scalable salt shed designs that can be used as a basic template depending on a DOT’s salt storage needs.
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.
This new Clear Roads synthesis project surveyed member states and other winter maintenance professionals and reviewed relevant literature to gain a greater understanding of current practices for the in-house production of brine.
