What were early roads made out of?

Early roads were typically made from natural materials such as dirt, gravel, stone, and wood. In ancient civilizations, like the Romans, roads were constructed using layers of stones, crushed rock, and sometimes clay to ensure durability and drainage. These materials varied based on the local resources available and the intended use of the road, with some roads being more sophisticated and engineered for heavy traffic and military movement. Over time, advancements led to the use of more refined materials, including cobblestones and eventually asphalt and concrete.
