| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Roads (roads) | historical_predecessor | 82% | expert_inference | Layered Roman surfacing is a refinement of engineered road construction, anchored by the Via Appia program beginning in 312 BCE. |
|
| Concrete (concrete) | common_dependency | 50% | weak_inference | Concrete-like binders may support some Roman road layers, but stone paving and drainage are the core scoped features. |
|
| Military Engineering Corps (military_engineering_corps) | commercial_or_scaling_dependency | 72% | expert_inference | The Via Appia was conceived as strategic military infrastructure, so organized state/military engineering explains scale rather than being a literal material prerequisite. |
