I would think you can safely assume highway=motorway is paved (and probably highway=motorway_link as well) even in the most desolate of countries (those that cannot afford to pave will simply have nothing higher than highway=trunk). Beyond that it's going to depend on the country and the part of the country. In many rural areas (definitely in Texas, but probably most of the US) highway=residential and highway=unclassified are usually not paved, and further I wouldn't expect them to be explicitly tagged with the likes of surface=unpaved or a more specific value implying lack of paving. This, though, is due a lot of rural roads in the US coming from TIGER data and still, to this day, at least a fair amount of it is untouched and may never meet certain standards for accuracy (I've been known to refer to phantom roads that originated from the TIGER import as "TIGER barf"). Even in greater Houston, I've seen many highway=service that are obviously unpaved. For many years, the street that the house I am in backs up to (next door to the house I grew up in) was a gravel road; it was finally paved sometime in the mid-1980s. This is long after every other house in the subdivision was paved (this area used to be out in the sticks back in the 1950s, where I-610 marked more or less the end of the urbanized area, but had long since been annexed by the City of Houston). -- Shawn K.
