Development and Outdoor Testing Based on Monitoring Data and Finite Volume Models of Cool Asphalt Prototypes in HE MULTICLIMACT

The MULTICLIMACT project (MULTI-faceted CLIMate adaptation ACTions to improve resilience, preparedness, and responsiveness of the built environment against multiple hazards at multiple scales) aims to provide an integrated framework of tools to assist public actors and citizens at territorial, urban and individual building level. During the second year of this project, two outdoor cool asphalt pavement prototypes to mitigate heat islands at urban scale for the city of Barcelona, together with the corresponding reference sample, have been monitored and analyzed. Data has been collected from a monitoring system measuring the temperature of the asphalt of the three constructed samples and evaluated with a parametric Finite Volume Method model for thermal analysis. This model fits the monitoring system data and enables to infer the impact that the pavement would have on pedestrians. With the results of this study, which is presented halfway through the development and testing phase of the project, the first conclusions based on real data and analytical models on these designed asphalt solutions are obtained, and the elaborated finite volume models are validated as a reliable tool to fit the monitored reality. This will allow to evaluate feasible modifications in the final design of the cool asphalt pavement that will be deployed in a demonstration installation in the city of Barcelona in the next year of the MULTICLIMACT project.
