WTI researchers initiate a “Black Ice” event for the Pacific Northwest Snowfighters

WTI researchers initiated a “Black Ice” event for the Pacific Northwest Snowfighters. The goal of this event is to evaluate the duration corrosion inhibitors last when applied to pavement in anticipation of frost or black ice. Applications of three inhibited chloride chemicals were sampled immediately after application and will continue to be sampled for the next seven days in order to quantify the presence of the corrosion inhibitors. The behavior of these chemicals, applied side by side, relative to changing air and pavement temperature and humidity will also be observed during the week.
