Abstract
A fluid pavement sealer composition includes a liquid phase having a sealant component and a fluid component, and at least about 25% by volume of finely divided metal particles suspended within the liquid phase. An electrically heated element contacts a pavement surface, with the solidified pavement sealer layer covering a selected area of the pavement surface including the electrically heated element. The solidified pavement sealant layer includes at least about 25% by volume of finely divided metal particles. The electrically heated element transfers heat to the pavement sealant layer and metal particles therein to maintain the selected area of pavement surface free of ice and snow.
