Natural events affect road performance, causing traffic disruptions and increased travel time. Road agencies face the dilemma of selecting more cost-effective alternatives for recovering the road performance, minimizing the costs, recovery time, and the loss of serviceability. The paper aims to develop a model integrating the cost-saving and the resilience evaluation to prioritize recovery strategies. Indexes are proposed to estimate the relative change in resilience, road agency and user costs produced by various recovery strategies from a base strategy. Both indices are integrated into a priority index that combines resilience, cost savings and redundancy. The procedure was applied to a case study in which earthquakes were simulated using recurrence models previously calibrated for Chile. Its effect on a simple road network composed of road platforms and bridges was estimated. The priority index was sensitized concerning traffic, damage of the road platform, and re-routing length. It was concluded that the variation in resilience and costs associated with recovery strategies cannot be considered as separate prioritization criteria, especially when changes in one or other decision variable are small.

自然事件会影响道路性能，导致交通中断并增加出行时间。道路机构面临选择更多具有成本效益的替代方案来恢复道路性能，最小化成本，恢复时间和维修性损失的困境。本文旨在建立一个模型，该模型整合了成本节省和弹性评估，以优先考虑恢复策略。提出了一些指标，以估计基本策略中各种恢复策略所产生的弹性，道路代理和用户成本的相对变化。这两个索引都集成到一个优先级索引中，该优先级索引结合了弹性，成本节省和冗余。该程序应用于案例研究，其中使用先前为智利校准的递归模型来模拟地震。估计了它对由路平台和桥梁组成的简单路网的影响。优先指标涉及交通，路平台损坏和重新路由长度。结论是，与恢复策略相​​关的弹性和成本的变化不能被视为单独的优先级标准，尤其是当一个或其他决策变量的变化较小时。
