The pavement condition index (PCI) is a tool for evaluating pavement performance and is based on the type and severity of surface distress. It is used to determine maintenance times, methods and location priorities. Most previous PCI prediction models have considered only pavement age or traffic volume as a variable, without consideration of other factors that affect pavement distress. In this study, data from 12 airports were analysed using reports published from 1994 to 2013. The airport pavements were divided into homogeneous zones according to their function and structure. For improved management of concrete airport pavements, a non-linear PCI model was developed for the homogeneous zones and tornado diagrams were used to analyse the sensitivity of the PCI according to the independent variables of the model. The results showed that the developed model can predict the PCI of homogeneous zones of concrete airport pavements more reasonably by considering various factors that affect pavement distress.

混凝土机场路面均质区非线性 PCI 模型的开发

路面状况指数 (PCI) 是一种评估路面性能的工具，它基于表面破损的类型和严重程度。它用于确定维护时间、方法和位置优先级。大多数以前的 PCI 预测模型只考虑了路面年龄或交通量作为变量，而没有考虑影响路面破损的其他因素。在这项研究中，使用 1994 年至 2013 年发布的报告分析了来自 12 个机场的数据。机场路面根据其功能和结构被划分为同质区。为了改进混凝土机场路面的管理，为均匀区域开发了非线性 PCI 模型，并使用龙卷风图根据模型的自变量分析 PCI 的敏感性。
