MACADAMISING

Macadamising is a form of road surfacing introduced to Britain by John McAdam, in 1816. The process involves covering the road surface with small, broken stones, so as to form a smooth, hard, convex surface - the surface being convex so as to allow water to run off to the sides. Today the stones are mixed with molten asphalt and compressed by a roller.
