This chart shows the percentage of roads paved by country.
Paved roads are those surfaced with crushed stone and hydrocarbon binder or bituminised agents, with concrete, or with cobblestones, as a percentage of all the country's roads, measured in length.
Road surface or pavement is the durable surface material laid down on an area intended to sustain vehicular or foot traffic, such as a road or walkway. In the past, gravel road surfaces, cobblestone and granite setts were extensively used, but these surfaces have mostly been replaced by asphalt or concrete laid on a compacted base course. Road surfaces are frequently marked to guide traffic. Today, permeable paving methods are beginning to be used for low-impact roadways and walkways.
