Title: Quality in Spreading -- Reducing Impact on Environment by Addressing Precision in Distribution of Ice Control Agent Spreading Technologies
Accession Number: 01152644
Record Type: Component
Availability: Transportation Research Board Business Office 500 Fifth Street, NW Abstract: Traditional technologies in spreading ice control agents cause a considerable waste of salt. Measurements of spreading quality indicate that at least (almost) half the amount of ice control agents consumed do not have any effect on winter maintenance. The effect is illustrated by a scenario. Simple salinity measurements are used to find the distribution of salt across a road section. The spreading quality is expressed as the standard deviation of the waste of salt due to imbalance between the lanes in the spreading patterns, while it is assumed that spreaders can be adjusted to eliminate systematic bias. The road authorities should focus on the spreading quality when ordering new spreaders, they should be aware of the stability in the spreaders adjustments, and they should introduce simple tests to verify that the adjustment, and thus the spreading quality, of each spreader is remained. This is the only way it will be possible to reduce the enormous unnecessary impact on the environment. In addition, the costs will be reduced as well.
