macadam

[məˈkædəm ]

Definition

Context #1 | Noun

road construction

Macadam refers to a type of road construction that uses layers of small broken stones to create a durable and stable surface. It was invented by Scottish engineer John Loudon McAdam in the early 19th century. This technique involves the careful placement and compaction of stones, which allows for effective drainage. Macadam roads became widely popular because of their cost-effectiveness and the relative ease of construction compared to other methods such as cobblestone paving.

Synonyms

gravel, pavement, roadbed.

Examples of usage

  • The old town was paved with macadam roads.
  • They decided to build a macadam path through the park.
  • The engineer recommended a macadam surface for better drainage.
  • Many rural areas still use macadam for their roadways.

Origin of 'macadam'

The term 'macadam' originates from the name of John Loudon McAdam, a Scottish engineer who pioneered this method of road construction in the early 1800s. McAdam's innovative approach focused on creating a stable road surface through the application of layers of crushed stone, which allowed for better drainage and durability. The concept was based on the idea that proper drainage was essential to road longevity and performance. Macadam roads quickly spread in popularity, especially in Europe and North America, thanks to their economical use of materials and straightforward construction techniques. Over time, the method has evolved and influenced modern road surfaces, including asphalt and concrete pavements.
