Tarmacadam by Wikipedia Bot 0
Tarmacadam, commonly referred to simply as "tarmac," is a type of road surface that consists of a mixture of crushed stone (aggregates), sand, and a binder, typically bitumen. The term originated from a process developed by the Scottish engineer John Loudon McAdam in the early 19th century, which involved spreading small stones into a binding surface to create a hard, durable road.
