Title: This is Why Roman Roads Last 2000 Years 🏛️🛣️

The ancient Romans didn’t just build roads — they engineered stone highways so durable that many are still intact and in use today, more than two millennia later. So what was their secret?

It wasn’t just one innovation — it was a layered system of brilliant engineering, meticulous labor, and smart design:

🔧 The Multi-Layer Masterpiece:

1. Statumen: A foundation layer of large, flat stones set in clay or sand.
2. Rudus: A middle layer of crushed rock mixed with lime and rubble for drainage.
3. Nucleus: A finer gravel and cement mixture that formed a solid base.
4. Summum Dorsum: The top layer — interlocking, hard volcanic stone blocks fitted tightly together in a slight convex shape to shed water.

💡 Why They Lasted:

· Drainage: The camber (curve) of the road allowed rainwater to run off, preventing erosion.
· Materials: They used local volcanic ash and lime to create a primitive but effective concrete.
· Labor: Built by legions of soldiers and skilled laborers with painstaking precision.
· Standardization: Roads were built to standard widths and gradients across the empire.

These roads connected an empire spanning three continents and enabled the rapid movement of troops, trade, and culture. Many modern roads still follow the original paths laid down by Roman engineers.
