摘　　要：西藏东南部特殊的气候条件引起的沥青路面病害直接影响到路面的使用性能和路面的耐久性,它与沥青混合料类型、混合料的配合比设计、沥青品质、矿料质量、施工方法与材料的均匀性、气候特点、交通条件等有关。通过调研分析了病害与藏东南独特的气候关系,冻土、巨大的昼夜温差、长时间高频率的降雨是造成路面病害的主要因素。The distresses of asphalt pavement in southeast Tibet with direct impact on pefformance and durability of pavement are analyzed in terms of bituminous mixture type, mixture design, quality of mineral aggregate, construction control, uniform of mixture, climate characteristics, and traffic condition, etc. as well as relations of the factors based on investigation. It is concluded that the main factors are climate in the southeast Tibet,frozen soil,great thermal difference between day and night,long-lasting with and high frequency.
