Macadam: adjective - from John Loudon McAdam (1756–1836), a British surveyor; of the kind of roadway laid down by McAdam; macadamized (tarmacadam) noun - material of which a macadamized road is formed.
'Black and twisting, the macadam road snaked across the landscape, forming a barrier between the two sorts of ground it divided, with the uncultivated wilderness to the east and the tamed farmland to the west.'
