Abstract: The originality of this study resides in taking into account the effect of the heat flux, the surface layer thickness and the rate of voids in the interface on temperature distribution within surface course. In this work, a numerical simulation was performed, which aim at studying the amplitude of the temperature distribution differs under the effect of the variation of the heat flux, the variation of the thickness of the surface layer and the rate of voids in the interface. The numerical simulation carried out to determine the effect of each of these factors, showed that the distribution of the temperature remains very sensitive to the increase of the flux but the influence of the other two factors less significant. The contribution of this work proposes a means of helping pavement engineers to design structures with excellent performance that are much more resistant to temperature fluctuations throughout the pavement life span.
