Can sensor-based noise mapping be a proxy of PM and permeability mapping?

In recent decades, road infrastructures have been the subject of numerous studies, aimed at ensuring reduced air and acoustic pollution. On the other hand, several studies showed that another important problem is dust load. Indeed, for internal combustion engine (ICEVs) and electric vehicles (EVs), suspended solids, fine particles, heavy metals, nutrients and organic chemicals can lead to a gradual reduction in terms of drainage characteristics, negatively affecting road acoustic characteristics. The purpose of this study is to discuss if sensor-based noise mapping can be a proxy of particulate matter (PM) and permeability mapping. More precisely, the main objective of this study is to discuss conceptual analogies among noise, PM, and permeability mapping. Selected specimens were produced with and without crumb rubber.
