I don't think we should do asphalt classification -- too difficult for many cases, and very little value, especially in this case because it is not the "type" of asphalt, it is rather a "feature" of asphalt. Multiple features could exist in the same asphalt - e.g. it could have noise-canceling qualities, or it could have under-surface charging, or it could have solar panels integrated into it, or it could have high melting point so it works well under sun.
In other words, I think it should be a yes flag, something like noise_reducing_surface=yes On Thu, May 2, 2019 at 5:12 PM Florian Lohoff <f...@zz.de> wrote: > On Thu, May 02, 2019 at 07:55:40PM +0000, amilopow...@u-cloud.ch wrote: > > Hello > > > > I used to live in Fribourg, Switzerland where they put "whispering > > asphalt" on one of the main roads in order to prevent noise.
