Pervious concrete pavement (PCP) is gaining popularity for many municipal and other applications in cold-climate regions. As part of winter maintenance operations to prevent pedestrians’ slipping accidents on sidewalks, deicers are typically applied to the pavement surface. The exposure to deicing chemicals can cause deterioration of the pavement structure, therefore it is critical to apply deicers at the proper surface temperature. In this study, thermal conductivity was characterized in the laboratory for pervious concrete as a function of porosity. A temperature prediction model was developed for an instrumented PCP sidewalk to predict the surface temperature of PCP during the winter season using Enhanced Integrated Climatic Model (EICM) finite-difference computer software. The objective of the study was to predict the winter days that the PCP surface may have potential to freeze based on local ambient conditions. The model can be used as a groundwork for the development of winter maintenance operation procedures for PCP in the future.
