Definition
Macadam is a type of road construction pioneered by John Loudon McAdam. It involves layering compacted, angular stones of uniform size to create a durable surface. Think of it as the predecessor to modern asphalt roads. Unlike earlier road construction methods, macadam didn't rely on large paving stones. It provided a smoother, more cost-effective surface. It revolutionized road building in the 19th century. 🛣️
