Analysis methodology and assessment indices of vulnerability for asphalt pavement in cold regions

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