text: The issue is currently discussed in https://github.com/westnordost/StreetComplete/issues/1762 : whether the StreetComplete UI should be changed to offer a better guide how to answer in cases like these or similar ones.
  
  tl;dr: My advice to you, as the author of StreetComplete, is to tag oil-bound macadam as "compacted" if it looks as and behaves like a generic "compacted" surface (like water-bound macadam) or to tag it as "asphalt", if it looks and behaves similar to asphalt.
  The third option, if you think "neither!", is to answer "Paved (generic)"
