How Did the Romans Build Roads That Still Stand After 2,000 Years?

Some Roman roads have survived for nearly 2,000 years, while modern roads can develop cracks and potholes in just a few years. What did ancient engineers understand about stone, soil, and water that helped their roads endure? Discover the engineering principles hidden beneath these ancient routes—and why the real secret wasn't one special material. In this video: How Roman engineers planned roads across difficult terrain Why layers of stone and gravel created stronger foundations How drainage protected roads from rain and erosion What Roman concrete could do—and where it was used Why water, traffic, and temperature damage modern roads What ancient road builders can teach engineers today Sources: Encyclopaedia Britannica — Roman Roads UNESCO World Heritage Centre — Ancient Roman Roads and Archaeological Sites Vitruvius — De Architectura (On Architecture) National Academies of Sciences, Engineering, and Medicine — Pavement Engineering Research American Concrete Institute — Roman Concrete and Ancient Construction Materials Subscribe to Brushwhy for a new ink-painted story every week. #explained #why #RomanRoads #AncientRome #Engineering
