statumen
Quick Summary
The statumen was a foundational layer in Roman road construction, typically 10 to 24 inches thick. It was composed of stones at least 2 inches in size, laid within parallel trenches that facilitated drainage. This layer was part of a larger, sophisticated Roman road-building technique that prioritized straightness and durability, often using concrete made from volcanic ash and lime. The Romans built an extensive network of roads, totaling nearly 53,000 miles, primarily for military, economic, and administrative advantages, connecting their vast empire from Britain to North Africa and the Middle East.12
