Abstract

In the context of its adaptation to climate change, the city of Paris has been experimenting pavement-watering since 2013. More recently, in the context of the LIFE “Cool & Low Noise Asphalt” project, innovative pavements were studied in combination with pavement-watering from summer 2019 to 2021. In this paper, the analysis focuses on the performance of pavement-watering conducted on two innovative and one standard pavements deployed rues Frémicourt and Lecourbe. Microclimatic conditions were monitored using fixed weather stations at each location measuring air temperature and humidity, wind speed and black globe temperature, used together to calculate mean radiant temperature. Pavement-watering impacts on Urban Heat Island (UHI) intensity and pedestrian heat stress were determined using air temperature and the Universal Thermal Climate Index (UTCI), respectively. For each pavement, statistically significant effects were observed. Results show maximum reductions between −0.7 to −0.9 °C of air temperature and between −1.5 and −2.2 °C UTCI-equivalent temperature with effects lasting from 3.2 to 7.1 h during the day. No statistically significant effects are observed on UHI intensity at either site. Additional experiments will allow the study of dry pavement performance and the optimization of watering.

路面浇水冷却效果应用于两条创新路面：来自LIFE“凉爽低噪音沥青”项目的案例研究

为适应气候变化，巴黎市自 2013 年以来一直在进行路面洒水试验。最近，在 LIFE "Cool & Low Noise Asphalt "项目的背景下，从 2019 年夏季到 2021 年，对创新型路面与路面洒水相结合的情况进行了研究。本文重点分析了在 Frémicourt 路和 Lecourbe 路铺设的两条创新路面和一条标准路面上进行路面洒水的效果。在每个地点使用固定气象站监测微气候条件，测量空气温度和湿度、风速和黑球温度，并共同计算平均辐射温度。分别使用空气温度和通用热气候指数（UTCI）确定路面浇水对城市热岛（UHI）强度和行人热应力的影响。对于每种路面，都观察到了统计学上的显著影响。结果显示，最大降温幅度在气温-0.7 至 -0.9 °C、UTCI 等效温度-1.5 至 -2.2 °C之间，影响持续时间为白天 3.2 至 7.1 小时。在这两个地点都没有观察到对 UHI 强度有明显的统计影响。更多的实验将有助于研究干燥路面的性能和浇水的优化。
