straking
n.— «Mahesh said the Department of Transportation had been applying magnesium chloride to New Mexico roads for about five years. It is a commonly used chemical to de-ice roads throughout the United States. It must be mixed to the right consistency and is then emptied from a tank onto the road in a process called straking. The chemical prevents the snow from binding to pavement and also melts some snow that falls on the roadway. The chemical works best when applied before a snowstorm.» —“Fatal crash: Highway department halts use of de-icer” by Natalie Storey New Mexican (Santa Fe, New Mexico) Dec. 17, 2006.
