Abstract: Asphalt concrete must often endure a range of different weather conditions, and its thermal conductivity is affected by these changes. Using the Finite Element Method (FEM), this paper develops a two-dimensional numerical model used to study and predict environmental effects and validates it through experimental results from the transient plane source method. It was also shown that an increase in the ratio of the TPS sensor size to the maximum size of the aggregate improves the accuracy of the measurements.
