Title:

Development and Validation of a Model to Predict Pavement Temperature Profile

Abstract:

To determine in-situ strength characteristics of flexible pavement, it is necessary to predict the temperature distribution within the hot-mix asphalt (HMA) layers. To determine the pavement temperature profile, the influence of ambient temperature and seasonal changes must be understood such that the effects of heating and cooling trends within the pavement structure can be quantified. It is possible to model daily pavement maxima and minima temperature by knowing the maximum or minimum ambient temperatures, the depth at which the pavement temperature is desired, and the day of year at a particular location. This paper extends that model to incorporate either the calculated daily solar radiation or latitude such that the model can be applied to any location.
