👉 Edgar Purnell Hooley in the context of Tarmacadam
Tarmacadam or tarmac is a concrete road surfacing material made by combining tar and macadam (crushed stone and sand), patented by Welsh inventor Edgar Purnell Hooley in 1902. It is a more durable and dust-free enhancement of simple compacted stone macadam surfaces invented by Scottish engineer John Loudon McAdam in the early 19th century. The terms "tarmacadam" and "tarmac" are also used for a variety of other materials, including tar-grouted macadam, bituminous surface treatments and modern asphalt concrete.
