摘　　要：针对季冻区公路沥青路面的破损问题,文章分析了季冻区的气候条件,沥青路面病害类型、破坏机理及施工技术要点,认为季冻区路面病害产生的原因是由于温度交替变化导致沥青路面力学性质的改变。文章给出了季冻区沥青路面抗冻技术的施工方法,该方法有效缓解了季冻区沥青路面的破损问题,可为类似问题提供可靠的施工技术依据。In this article, for the damage of asphalt concrete pavement in the seasonal frozen areas, the climatic conditions in the seasonally frozen areas, the types of asphalt pavement disease and its mechanism as well as the key points of construction technique were analyzed. It is concluded that the reason of the damage is that the mechanical properties of asphalt pavements change with the alternative change of the temperature.The construction method of the anti-freezing technology of the asphalt pavement in the seasonal frozen area is put forward, which effectively alleviates the damage of the roads, and also provide a reliable technical basis for similar problems.
