Radiative Cooling Benefits of Materials Applied to the Steel Furnace Slag Use in Asphalt Pavement in a City

Abstract:

The urban surface contains a large amount of asphalt concrete pavement, which is also one of the main causes of the urban heat island effect. This study aims to explore the effect of BOFS on radiative cooling when applied to asphalt concrete pavement, and to review it as strategies to mitigate the urban heat island effect. This study chooses the density grading certified by TAF commonly used by road design units at present. Setting up thermometers on the actual construction site, the temperature of each layer would be measured. It is hoped that through comparison at actual on-site paving of BOFS pellets and natural pellets, the difference in effectiveness in radiant cooling can be evaluated. The results show that BOFS pellets for road paving have significant potential for radiative cooling.
