Abstract

ABSTRACT The Urban Heat Island (UHI) phenomenon is commonly solved by implementing materials with optimal thermic and evapotranspiration properties which help decreasing the air temperature in dense urban areas. This approach has been applied in this study, testing six different materials (replacing the current Macadam) in one parking area in Bari (Italy), which provides a large-scale testbed, by means of a thermal three-dimensional non-hydrostatic simulation: impervious asphalt pavement (IAP), asphalt permeable pavement (APP), green pavement (GP), green pavement-asphalt permeable pavement (GP+APP), grey porous concrete blocks (GCB), and light concrete permeable pavement (LCPP). The highest-performance pavements in terms of potential air temperature (PAT) reduction were the GP (−1.22°C), GCB (−1.26°C) and LCPP (−1.22°C), which also showed a constant relative humidity, suggesting their UHI mitigation benefits. A comparison of the structural properties as well as the construction and maintenance costs of such pavements is also provided, finding the best mitigation strategy (GCB).

不同道路铺装类型对城市热岛的影响:个案研究

摘要城市热岛（UHI）现象通常通过使用具有最佳热和蒸散特性的材料来解决，这些材料有助于降低密集城市地区的空气温度。该方法已应用于本研究，通过热三维非流体力学模拟，在意大利巴里的一个停车场测试了六种不同的材料（取代了目前的Macadam），该停车场提供了一个大型试验台：不透水沥青路面（IAP）、沥青透水路面（APP）、绿色路面（GP）、，灰色多孔混凝土块（GCB）和轻质混凝土透水路面（LCPP）。就潜在空气温度（PAT）降低而言，性能最高的路面是GP（-1.22°C）、GCB（-1.26°C）和LCPP（-1.22℃），它们也显示出恒定的相对湿度，这表明它们具有缓解UHI的好处。还对此类路面的结构特性以及施工和维护成本进行了比较，找到了最佳缓解策略（GCB）。

期刊介绍： Sustainable and Resilient Infrastructure is an interdisciplinary journal that focuses on the sustainable development of resilient communities. Sustainability is defined in relation to the ability of infrastructure to address the needs of the present without sacrificing the ability of future generations to meet their needs. Resilience is considered in relation to both natural hazards (like earthquakes, tsunami, hurricanes, cyclones, tornado, flooding and drought) and anthropogenic hazards (like human errors and malevolent attacks.) Resilience is taken to depend both on the performance of the built and modified natural environment and on the contextual characteristics of social, economic and political institutions. Sustainability and resilience are considered both for physical and non-physical infrastructure.
