Prediction of Asphalt Pavement Temperature
Structural capacities of flexible pavements are determined from surface deflection measurements. These deflections must be corrected to a standard load and/or a reference pavement temperature. A number of models are available to predict pavement temperature. In this study, measured pavement temperatures were compared with the predicted (calculated) temperatures. The effect of temperature correction on the deflection under the load (center) was also investigated. The results show that there is a significant difference between calculated and measured temperatures at the pavement mid-depth for most models. Only one model yielded a mid-depth pavement temperature close to the measured value. The results also showed that the effect of temperature-correction method at times can be very pronounced. The most accurate model for correcting pavement surface deflections for temperature was identified.
