The Roman engineers created roads that went through natural obstacles rather than around them wherever possible. A Roman road consisted of two parallel trenches and a well drained core. Packed small stones were the foundation and the drainage system was the best the ancient world had ever seen. Layers of concrete and cement and concrete gravel made the roads durable. The top layer was made of gravel, packed stones and paving stones.

The Romans built about 10,000 miles of roads throughout the empire. Roman roads were made with sand, gravel, rocks and concrete and beveled to help water drain to the outer sections of the road. Whenever possible the roadways were made straight and ran through natural obstacles as best as their engineers could manage. The Roman engineers also used clay, mortar and volcanic lava rocks. The surface of the roads were usually rectangular stone slabs.
