摘　　要：着重分析了水泥混凝土与沥青混凝土复合式路面温度梯度的变化规律及其受沥青层厚度的影响状况，并结合我国各地气象资料，建立了一个适用于不同沥青层厚度、不同混凝土板厚度的计算混凝土板最大温度梯度的回归公式。The thermal gradient of ament concrete and asphalt concrete composite pavement which is influenced by the overlay thickness is analyzed. Considering the climate states of different areas, a formula to compute the maximum thermal gradient of composite pavement is presented by means of regression, which is suitable for different thickness of asphalt concrete overlay and cement concrete slab. This research is the basis of studying thermal stress of this composite pavement.
