The Effects of Heat Transfer on Flexible Pavement and Temperature Prediction Model in Taiwan
This study was to establish a suitable prediction model of pavement temperature to accommodate warmer subtropical climate and thicker pavement in Taiwan. Three typical pavement structures of freeway were constructed and instrumented to collect temperature measurements. Results showed that the peak temperature of AC layer occurred between 12:00 to 14:00, while that of BTB layer happened after 17:00. Outgoing radiation, convection energy, and conduction energy were found also influential to the pavement temperature. Two sinusoidal functions were fitted based on the representative monthly temperature measurements and validated for AC and BTB layers. It enables field engineers of highway agencies to assess FWD data conveniently and accurately by incorporating two proposed models with in-situ ambient and pavement surface temperature measurements.
