摘要:
以傅立叶导热定律为基本理论,依据一维稳态导热原理,自行开发了一套双试件平板式热传导试验装置,对3种不同类型的沥青混合料进行了热传导试验,测试了不同试验温度下沥青混合料的导热系数,分析了热传导性能。试验结果表明:沥青混合料的导热系数是一个温变值,随温度的升高而呈线性增加; 在相同温度条件下,不同类型沥青混合料的导热系数值相差较小; 开发的热传导试验装置稳定可靠,操作简便。
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. 4 tabs, 6 figs, 19 refs.
