Asphalt pavement structures in cold regions, which suffer from complicated environmental and geological conditions, such as large temperature difference and frozen soil, are prone to cracking, rutting, and moisture damage. However, most of the existing assessment methodologies focus on the vulnerability of the overall road traffic network, ignoring the impact of regional differences and pavements’ structural performance. To establish a highly targeted vulnerability analysis methodology for cold regional asphalt pavements, the concept of highway vulnerability and the assessment model composed of exposure, fragility, and resilience were proposed in this paper firstly. Meanwhile, the assessment indices and standards for exposure, fragility, and resilience were respectively discussed. Then, the calculation process for each index weight and vulnerability index was proposed based on AHP-fuzzy comprehensive assessment methodology. Consequently, the vulnerability grade of asphalt pavements in cold regions could be determined. Finally, the vulnerability assessment indices and methodology for cold regional asphalt pavements were illustrated and presented, providing a theoretical basis for asphalt pavement performance evaluation and vulnerability assessment serviced under cold regional climate.

寒冷地区沥青路面易损性分析方法及评价指标

寒冷地区的沥青路面结构易受复杂的环境和地质条件（例如温差大和冻土）的影响，容易开裂，车辙和湿气损坏。但是，大多数现有的评估方法都将重点放在整个道路交通网络的脆弱性上，而忽略了区域差异和人行道结构性能的影响。为了建立针对性强的冷区域沥青路面易损性分析方法，本文提出了公路易损性的概念以及由暴露，脆弱性和回弹性组成的评估模型。同时，分别讨论了暴露，脆弱性和韧性的评估指标和标准。然后，基于层次分析法-模糊综合评价方法，提出了各指标权重和脆弱性指标的计算过程。因此，可以确定寒冷地区沥青路面的易损等级。最后，阐述并介绍了寒冷地区沥青路面的脆弱性评估指标和方法，为寒冷地区气候下沥青路面性能评估和脆弱性评估提供了理论基础。
