This synthesis reports on how airports chemically treat their airport pavements to mitigate snow and ice, and the chemicals used; reviews the effects of pavement deicing products (PDPs) on aircraft and airfield infrastructure; and describes critical knowledge gaps in the subject. This report is technical in nature. Effects of PDPs on airport components include description of catalytic oxidation of carbon-carbon composite brakes, cadmium corrosion, and chemical interaction of aircraft deicing and anti-icing fluids on airfield infrastructure, including concrete and asphalt pavements and metal and composite fixtures such as runway lights.
