road surface
Asphalt or concrete
Road surface is the material layer of a road that vehicles drive on—asphalt, concrete, gravel, or packed earth.
The term appears in discussions of infrastructure, driving conditions, and maintenance: The road surface was cracked and pitted after the harsh winter.
British English uses road surface where American English often prefers pavement or roadway.
