The amount of deicing or anti-icing material that is applied to a specific area of a roadway, multi-use path, sidewalk, or parking lot during winter operations. This is usually measured in pounds per unit area, e.g. pounds per lane mile, kilograms per lane kilometer, or pounds per square yard. The application rate can vary based on a number of factors, including the pavement temperature, the type of material being used, the severity of the weather conditions, and the amount of traffic.
