What does macadamize mean?
Macadamize means to pave a road or path with macadam, a durable surface made from compacted crushed stone. The method became associated with the Scottish engineer John Loudon McAdam, who advocated building roads in layers of small stones that were compacted by traffic and rain. Although the term is now largely historical, it remains useful in accounts of early road building and in descriptions of roads laid in the traditional macadam fashion. The verb can also be used more broadly when a surface of crushed stone is applied to a track or path. Its modern counterpart is often the simpler verb “pave,” while “macadam” by itself usually names the material rather than the action of applying it. The word is especially associated with British and American road engineering during the nineteenth century.

Where does macadamize come from?
The word derives from the surname of the Scottish engineer John Loudon McAdam, whose method of constructing roads with compacted crushed stone was widely adopted in the early nineteenth century. The related noun macadam came to name both the road-building method and the crushed-stone material used in it. The verb macadamize developed with the spread of McAdam’s system, although the practice eventually became largely obsolete as other paving methods took over.
