| 摘 要： | 对国道214公路部分试验监测路段水泥混凝土路面和沥青混凝土路面下的温度场进行了分析和研究。研究结果表明,路面类型对路基温度场有一定的影响,在多年冻土地区,水泥混凝土路面下路基温度场的改变程度明显比沥青混凝土路面下小。这说明在多年冻土区,采用水泥混凝土路面比采用沥青混凝土路面更有利于改善路基温度场的稳定。

| Abstract: | This paper analyzed the thermal regime of roadbeds both under asphalt concrete pavement and cement concrete pavement in G214 expressway according to the ground temperature in recent three years.It shown that the pavement types have great infuence on the thermal regime of roadbed,and the influence on the thremal regime under cement concrete pavement was less than that under asphalt conerete pavement in permafrost regions.Therefore,it is better to use cement concrete pavement than asphalt concrete pavement for keeping the heat stability of roadbed in permafrost regions.A series of conclusions were drown from this research. |
