Melt, baby, melt

摘要

In the first U.S. application of a solar-powered anti-icing/de-icing system on bridges, Missouri DOT (MoDOT) is testing how well the sun melts away winter weather maladies on two structures.rnThe surface heating system prevents snow, ice, and especially black ice from forming on pavement while also serving as an alternate energy source.rnFunctioning similarly to radiant heating in a home's floor, the method involves installing tubing in the bridge deck and pumping a heated, antifreeze, water/gly-col solution through the 5/8-inch polyethylene tubes to keep the deck from freezing.
