It has been found that maintenance costs for gravel roads often exceed the maintenance costs for paved or surface-treated roads when traffic volumes exceed 200 vehicles per day. [51] Pavement ends and turns into gravel surface road. Some communities are finding it makes sense to convert their low-volume paved roads to aggregate surfaces. [52]

Azerbaijan has about 29,000 km (18,000 mi) of paved roads; the first paved roads were built during the Russian Empire.

Parking lots are highly impervious.. Impervious surfaces are mainly artificial structures—such as pavements (roads, sidewalks, driveways and parking lots, as well as industrial areas such as airports, ports and logistics and distribution centres, all of which use considerable paved areas) that are covered by water-resistant materials such as asphalt, concrete, brick, stone—and rooftops.
Only fully paved roads of which both ends are connected to the main Swiss or European road network are included. Dead-end roads such as the Sanetsch and Glas Pass are not listed. For a list including dead-end roads as well, see list of highest paved roads in Switzerland. For a list of all passes, whether crossed by a paved road or not, see List ...
Sidewalks are a common form of hardscaping. Hardscape is hard landscape materials in the built environment structures that are incorporated into a landscape.
