Abstract: Deicing and anti-icing performance of an innovative polyurethane pavement surface layer that replaces asphalt binder was studied. Thermal properties of polyurethane concrete and asphalt concrete were measured using a Hot Disk Thermal Constants Analyzer with transient plane source (TPS) method. Results found that polyurethane concrete had similar thermal conductivity to asphalt concrete, but a much greater specific heat. Polyurethane was also found to have a better anti-icing and deicing performance compared to asphalt concrete.
