MACADAM

Macadam

Macadam is a type of road construction pioneered by Scottish engineer John Loudon McAdam in around 1820. The method simplified what had been considered state of the art at that point. Single-sized aggregate layers of small stones, with a coating of binder as a cementing agent, are mixed in an open-structured roadway.
