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.
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.
Clear Roads project 18-03, Evaluation of SSI and WSI Variables, produced a step-by-step guide and flowchart tool to help agencies identify or develop severity index methods to fit their needs and available data sources.
As estimating the impact of weather on roadway maintenance resources is becoming an increasingly important issue for agencies across the country, a recently completed Clear Roads project, 21-04, produced additional training modules geared toward three key audiences: division directors, snow and ice managers, and supervisors.
