I also would not introduce a new surface value, it is still asphalt. Either you see it as an additional property like<br>
asphalt:noise=low (thinking of eventually 2-3 values like low/default/noisy), which would open a whole field of asphalt properties (asphalt:drainage, ...) or if „whispering asphalt“ is really considered a type of asphalt on its own, a subtag for an asphalt class:<br>
asphalt=whispering or porous...<br>
(or the synonymous asphalt:type asphalt_type,...)<br>
<br>
I would tend to the former<br>
asphalt:noise=low<br>
<br>
(concise and easy to understand)<br>
<br>
Cheers, Martin <br>
