This was followed by foundation layers of crushed rocks or gravel cemented with lime mortar. The bottom section of the road was usually made of leveled earth and mortar or sand topped with small stones. Crews began by digging shallow, three-foot trenches and erecting small retaining walls along either side of the proposed route. Roman builders used whatever materials were at hand to construct their roads, but their design always employed multiple layers for durability and flatness. Britain’s Fosse Way, for example, only veered a few miles off course over its entire 180-mile distance.
