Mac Adam, 1829 pavé à la Mac-Adam ); similarly macadamiser (1827), macadamisage (1827), mac-adamisation (1830). Reported in oral use in 19th cent. in form muckydam (probably after mucky adj.):1861 H. Mayhew London Labour (new ed.) II. 470/2 When it was paved, afore this muckydam (macadamising) was turned up, a broom would last me a full three months. I can't abide this muckydam..it's sloppy stuff, and goes so bad in holes.

A. adj.
