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.
With better decision-making tools, agencies of all sizes can avoid applying too much salt to their roads, saving time, money and the environment.
