摘　　要：本文应用热传导理论建立碾压混凝土与沥青混凝土复合式层状路面结构的分层热传导方程，并通过总换热系数的反演分析、路表复合传热机理及材料热物理特性的研究，建立路面结构非稳态导热定解条件，再导出层状路面结构复合体的差分方程，求解瞬时温度场。文中讨论了碾压水泥混凝土与沥青混凝土复合式路面结构温度场变化规律，文后给出全国各自然区划中此型式路面的碾压水泥混凝土板最大温度梯度。In this paper, the heat conduction equation of roller-compacted concrete pavement with asphalt concrete overlay is established according to heat conduction theory. The boundary condition and initiative condition of a non-stabilization conduction of heat in the pavement is determined by studying the complex heat conduction mechanism of pavement and the heat-physics properties of material. Intantaneous temperature field in the layered pavement is evaluated by differential equation. The variation of temperature field in the pavement is discussed. The maximum temperature gradient of RCCP around the country is also given.
