AFAIK porous asphalt (which is often called draining asphalt here) is a very good thing (for rain) and driving (braking/adherence is excellent) but not particularly good for noise. https://en.wikipedia.org/wiki/Permeable_paving#Porous_asphalt https://en.wikipedia.org/wiki/Permeable_paving#Porous_asphal... it is largely used in highways, actually near 100% of highways in Italy are paved with this kind: https://www.autostrade.it/en/tecnologia-sicurezza/sicurezza/pavimentazione-asfalto-drenante https://www.autostrade.it/en/tecnologia-sicurezza/sicurezza/... Since several years they are experimenting in various EU cities, particularly for roads restricted to buses, a type of asphalt that incorporates (recycled) rubber which reduces effectively a part of the noise and vibrations, but is seemingly used in US too: https://en.wikipedia.org/wiki/Rubberized_asphalt https://en.wikipedia.org/wiki/Rubberized_asphalt
