【摘要】 通过分析多年冻土区典型公路G214沿线不同冻土条件下沥青和水泥混凝土路面病害状况,对两种路面类型的路面病害分布规律及其差异进行了分析,并就当前多年冻土地区两种类型路面的适应性问题进行了探讨。在路面病害分析过程中,采用现场踏勘的方法首先对路面病害类型、病害程度等进行调查和统计,然后就两种路面类型病害分布差异及产生原因进行了分析和讨论。最后通过分析得出多年冻土地区两种类型路面的病害分布规律差异状况,以及在多年冻土地区两种类型路面的适应性差异。更多还原

【Abstract】 The distribution patterns of distresses in both cement concrete pavement and asphalt pavement were analyzed based on field investigations along the typical highway G214 in different permafrost regions,and the difference of adaptability in both cement concrete pavement and asphalt pavement in permafrost regions was also discussed.First,the statistics of types,extents and distribution patterns of distresses of cement concrete pavement and asphalt pavement were obtained by field investigation.Then,the differences and reasons of the distress distributions of the two pavement types were discussed.At last,the differences of distress distributions and adaptabilities of the two pavement types in permafrost regions were obtained.更多还原
