WTI researchers completed a man-made snow event for the Pacific Northwest Snowfighters Inhibitor Longevity and Deicer Performance Study. The goal of this event was to evaluate corrosion inhibitor longevity in anti-icers after roadway application following a significant snow event. Three inhibited chloride anti-icers were applied with a specially designed applicator trailer. Snow production began following anti-icer application and continued until a uniform layer of fine crystalline snow was achieved. Test sections were sampled for seven consecutive days with testing of the anti-icers for longevity parameters currently underway at the Corrosion and Infrastructure Laboratory at WTI.
