Abstract

Flooding has been a great threat to the functionality and longevity of transportation infrastructure, particularly roadway pavements. This study utilizes a systematic approach to improve roadway resilience through comprehensive review and synthesis of existing knowledge and identification of current gaps. The study first reveals the diverse mechanisms of flooding-related risk, including surface material degradation, hydraulic scouring, subsurface saturation, subgrade erosion, and washout. It then explores non-destructive testing methods, and pavement performance modelling approaches for assessing flooding impacts through fragility curves, highlighting their respective advantages and limitations. Finally, various mitigation strategies are discussed, each offering unique benefits. These include nature-based solutions, roadway geometry adjustments, pavement design and maintenance enhancements, and post-flooding operation. Future research is recommended to better understand and prevent washout damage, characterize recovery period after flooding, and select mitigation strategies based on life-cycle assessment for improving infrastructure resilience under climate change.

提高道路路面抗水韧性：影响评估和缓解策略

洪水对交通基础设施的功能和寿命构成了巨大威胁，尤其是道路路面。本研究采用系统的方法，通过对现有知识的全面回顾和综合，以及对当前差距的识别，来提高巷道弹性。该研究首先揭示了洪水相关风险的多种机制，包括地表物质退化、水力冲刷、地下饱和、路基侵蚀和冲刷。然后探讨了无损测试方法和路面性能建模方法，通过脆弱性曲线评估洪水影响，突出各自的优势和局限性。最后，讨论了各种缓解策略，每种策略都提供了独特的好处。这些措施包括基于自然的解决方案、道路几何形状调整、路面设计和维护改进以及洪水后的操作。未来的研究建议更好地了解和预防冲毁损害，表征洪水后恢复期，并选择基于生命周期评估的缓解策略，以提高气候变化下基础设施的恢复能力。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
