is it an actual tarmacadan? In such case surface=tarmacadan may be a better less confused term (tarmac is widely used for asphalt and concrete surfaces)

Or is it just a regular asphalt surface? Then surface=asphalt would be better

see https://wiki.openstreetmap.org/wiki/Tag:surface=tarmac for some documentation
