病害类型是沥青路面养护决策的重要依据，病害类型之间的关系对沥青路面养护决策结果有很大影响。在这项研究中，从统计的角度来分析不同损坏类型之间的关系，282半刚性基层结构的沥青路面在中国23个地区进行了调查，以确定12损坏类型，随后进行了关联规则挖掘。研究结果表明，根据这些关系，车辙病害类型可分为独立病害类型（IDDT）、依赖病害类型（DDTs）和车辙次生病害类型（RSDTs）。IDDT之间的相关性最强，IDDT与DDTs之间、车辙与RSDTs之间以及洼地、抽水和松散之间的相关性也很强，而其他相关性较弱。在维修决策中，应忽略弱关系，而考虑强关系，以降低成本，保证维修决策的准确性。IDDT是最重要的损坏类型，因此预防它们的发生或立即维护它们可以极大地保持沥青路面的良好性能。为了帮助分析的关系，灾难类型的系统建立和验证。总之，这项工作提供了新的见解，以了解遇险类型。
Distress types are significant for asphalt pavement maintenance decision, and relationships among them can greatly influence the decision outcomes. In this study, to analyze the relationships among different distress types from a statistical point of view, 282 asphalt pavements with semirigid base structures in 23 regions of China were surveyed to identify 12 distress types, which were subsequently investigated by association rule mining. Results show that the distress types can be categorized into independent distress types (IDDTs), dependent distress types (DDTs), and rutting secondary distress types (RSDTs) based on the relationships. The relationships among IDDTs are the strongest, and those between IDDTs and DDTs, between rutting and RSDTs, and among depression, pumping, and raveling are also strong, while the others are weak. The weak relationships should be ignored, while the strong ones should be considered to reduce cost and guarantee accuracy of maintenance decision. The IDDTs are the most important distress types, so preventing them from occurring or maintaining them immediately can greatly preserve good performance of asphalt pavements. To help analyze the relationships, a distress-type system was established and verified. In conclusion, this work provides new insights to understand distress types.
