This study aims to integrate sustainability indicators into the traditional assessment of network-level pavement maintenance budget scenarios. A conceptual framework is developed based on a multi-attribute method by systematically considering road conditions, economic, environmental, and social sustainability. A case study is then adopted to demonstrate the usefulness of this framework. Out of eight network-level pavement maintenance budget scenarios, the 85M plan (representing an annual maintenance budget of AUD$85M) is selected as the optimal solution in an initial experiment in which equal weights are allocated to the four attributes. In an additional experiment with 1000 sets of randomly assigned weights, the 85M plan was also selected as the optimal option for 596 trials. The proposed framework provides a straightforward method for road agencies to select the optimal network-level pavement maintenance budget scenario or obtain preliminary insights when the precise weight of each sustainability attribute cannot be accurately obtained.

基于可持续考虑选择最优网络级路面维护预算方案

本研究旨在将可持续性指标整合到网络级路面维护预算情景的传统评估中。通过系统地考虑道路条件、经济、环境和社会可持续性,基于多属性方法开发了一个概念框架。然后通过一个案例研究来证明这个框架的有用性。在八个网络级路面维护预算方案中,85M 计划(代表 AUD$85M 的年度维护预算)被选为初始实验中的最佳解决方案,其中为四个属性分配了相等的权重。在 1000 组随机分配的权重的附加实验中,85M 计划也被选为 596 次试验的最佳选项。
