Macadam

Macadam refers to a type of road construction that involves layering crushed stone of varying sizes and then binding the stone together with a binder such as asphalt or bitumen. It creates a durable and relatively smooth road surface. This method was initially developed in the early 19th century by Scottish engineer John Loudon McAdam, who sought a cost-effective way to improve road infrastructure. Properly constructed macadam roads are resistant to weathering and heavy traffic. They allow for effective drainage, extending the lifespan of the road and reducing maintenance needs. macadam is widely utilized, particularly in road construction, parking lots, and driveways, offering a balance between cost, durability, and surface quality.
