Microclimatic Impact of Innovative Pavements for the Life Cool & Low Noise Asphalt Project
Résumé
In the wake of the heat-wave of 2003 along with the context of climate change, strong awareness has risen within the City of Paris regarding the need for urban cooling. Several experiments have been carried out including pavement-watering. In this context, the LIFE “Cool & Low Noise Asphalt” project aims to study the performance of pavement-watering on innovative pavements to reduce pedestrians heat stress on three test sites in the summer since 2019. Statistically significant air temperature reductions of up to -0.4°C were observed in addition to reductions of up to -0.6°C of UTCI-equivalent temperature. The impact of resurfacing the pavement and the combination of resurfacing and watering are also studied.
