NTL-HIGHWAY/ROAD TRANSPORTATION-Construction and Maintenance
Abstract:
This research developed and completed a field evaluation of salt distribution equipment. The evaluation provides a direct comparison of three different types of salt spreaders at three different truck speeds and brine rates. A rubber mat was divided into eight sample areas to measure the salt distribution across the lane by each variable combination. A total of 264 samples were processed and measured. These results will support future efforts to target areas of efficiencies specific to salt and brine delivery methods. These results support Iowa Department of Transportation efforts to progress winter maintenance efficiencies and ultimately motorist safety.
This project involves measuring and reporting the retention of salt and brine on the roadway as a result of using different salt spreaders, applicatio...
INDOT has successfully used salt brine in anti‐icing efforts as a way to deliver preventative treatment before an event (e.g. bridge deckfrost) occu...
