Abstract: Hydronic Pavement (HP) is a potential alternative method of spreading sand and salt on slippery road surfaces through embedded pipes that circulate brine, oils, or glycol-water. The present study analyzes the thermal properties involved in designing a HP system. The transient plane source method was used to analyze thermal properties of asphalt with various sensor sizes. Results showed that thermal conductivity varied around 6-14% based on the different depths of an asphalt pavement.
