The objective of this work is to examine the state of knowledge relevant to permeable concrete pavements (PCPs) and facilitate efforts in enhancing their overall performance and maximizing their environmental benefits. Based on a review of recent literature, this work provides a summary of the key environmental benefits of PCPs, in terms of stormwater runoff reduction, underground water quality improvement, heat-island effect mitigation, traffic noise reduction, and skid resistance improvement. The hydraulic performance of PCPs is determined by its mix design, pavement design, construction practice, and service environment. In general, it is difficult to simultaneously optimize the mechanical and durability properties and infiltration performance of PCPs. New technologies need to be developed to help improve the durability of PCPs without significantly increasing its maintenance requirements or sacrificing its infiltration properties. Freeze/thaw damage, deicer impacts, and clogging phenomenon still create bottleneck problems for the implementation of PCPs. The durability of PCPs in cold climates is governed by many factors, and advances could be made at many stages of its life cycle. Challenges remain in quantitative characterization of permeable concrete materials and in establishing quantitative relationships between the physicochemical characteristics and performance of permeable concrete. Modeling and advanced characterization are expected to greatly advance the PCP technology. This review also provides a look to the future, for instance, there are some emerging areas of research (e.g., nano-science and nano-engineering) that may help address the durability challenges or further enhance the environmental benefits of PCPs.

这项工作的目的是检查与可渗透混凝土路面（PCP）有关的知识状态，并促进提高其整体性能和最大程度地提高其环境效益的努力。在回顾最近文献的基础上，这项工作总结了五氯苯酚在减少雨水径流，改善地下水质量，减轻热岛效应，减少交通噪声和防滑性能方面的关键环境效益。PCP的水力性能取决于其混合料设计，路面设计，施工实践和使用环境。通常，很难同时优化PCP的机械性能和耐用性以及渗透性能。需要开发新技术以帮助提高PCP的耐用性，而又不会显着提高其PCP的维护要求或牺牲其渗透性能。冻结/融化损坏，除冰剂冲击和堵塞现象仍然为PCP的实施造成瓶颈问题。五氯苯酚在寒冷气候下的耐久性受许多因素制约，在其生命周期的许多阶段都可以取得进步。在可渗透混凝土材料的定量表征以及在可渗透混凝土的物理化学特性和性能之间建立定量关系方面仍然存在挑战。建模和高级表征有望极大地推动PCP技术的发展。这篇评论还提供了对未来的展望，例如，有一些新兴的研究领域（例如，
