It has been known that a stiffness of asphalt mixture varies with its temperature. A temperature prediction of asphalt mixture and a relationship between its stiffness and temperature constitute important elements when pavement life span is predicted.Pavement temperature depends solar radiation, air temperature, wind velocity, infrared radiation, thermal properties of materials constituting pavement. Focusing on the thermal properties, we present the method to estimate thermal properties of materials and discuss the estimates of thermal properties obtained from meteorological data and temperatures measured by thermocouples at our field test site. |
