Abstract

Abstract

Based on Fourier's heat conduction law and applying the principle of 1-D stable heat conduction, an experimental device in the form of double plane samples for heat conduction was self-developed, and the heat conduction experiments of 3 kinds of asphalt mixtures were done. The heat conductivities of asphalt mixtures at different temperatures were measured, and the heat conductibilities were studied. Experiment result shows that the heat conductivity of asphalt mixture changes with temperature, and increases linearly with the increase of temperature. There is not a great difference among the heat conductivity values of different asphalt mixtures at the same temperature, and the experimental device is stable and easy to handle.
