The research objective was to evaluate the temperature dissipation during the Hot Mix Asphalt construction from the surface, base, and subbase layers in Southern Taiwan. The scope was to install a multilayered temperature monitoring station along with the weather station that allows temperature data to be recorded and stored continuously. The multilayered temperature monitoring station was installed and comprised of K-type thermocouples. Thermocouples were installed from the surface in-depth 0, 5, 10, 15, 17, 20, 30, 42.5, 72.5, and 90-cm along with the construction sequences starting from base and subbase compaction on soils and graded aggregates in May 2018 and thereafter the paving task of HMA surface layer in August, 2018. It has to be noted that the temperature data was recorded immediately and continuously when thermocouples were installed which enables the monitoring of pavement temperature dissipation during the HMA construction. In this paper, we aim to present a temperature dissipation pattern that is able to improve and facilitate the field HMA paving task. It is nine hours or more, instead of six hour of which roadways agencies often regulate, that is required for HMA pavement materials to cool down and open for traffic.
